Shore excursions and onboard activities fill most of your day
A May cruise gives you access to the same activities and excursions available on any other sailing, but May timing affects which destinations are open and how crowded they are. Most cruise lines run organized shore excursions at each port—these are guided tours, water sports, cultural visits, or adventure activities that the cruise line has vetted and insured. You can book these before you sail or at the onboard excursion desk once you're aboard. Onboard, you'll find fitness classes, cooking demonstrations, trivia contests, live music, comedy shows, and themed dinners included in your fare.
The activities you can actually do depend on your ship's itinerary and your physical comfort level. A Caribbean cruise in May offers snorkeling, beach time, and water sports at most ports. A Mediterranean or Northern Europe cruise in May opens ports that are too cold or icy earlier in the year—you can visit Scandinavia, the Baltic, or Iceland in May when the weather is passable and the days are long. An Alaska cruise typically doesn't depart until mid-May, when glaciers are visible and wildlife is active.
Key Takeaways
- Shore excursions are organized tours and activities at each port that you book through the cruise line, and they range from guided city walks to kayaking and snorkeling.
- Onboard activities—fitness classes, shows, dining events, and games—are included in your cruise fare and run throughout the day and evening.
- May weather varies by region: Caribbean ports are warm and dry, while Northern Europe and Alaska are just becoming accessible for cruising.
- You can book excursions before you sail online or wait and book at the onboard desk, though popular activities may sell out.
- Ports in May are less crowded than summer months, which means shorter lines at attractions and more availability for excursions.
Shore excursions: what they include and how to book
Shore excursions are activities organized by the cruise line at each port of call. The cruise line contracts with local operators, handles insurance and liability, and guarantees the activity will get you back to the ship on time. You choose from a list of options—usually 10 to 30 per port—ranging from a two-hour guided walking tour to a full-day adventure like zip-lining, horseback riding, or scuba diving.
Most cruise lines let you browse and book excursions on their website before you sail. You'll see the price, duration, physical difficulty level, and what's included (lunch, equipment, transportation from the port). Prices vary widely: a basic city tour might cost $40 to $60 per person, while an all-day adventure or water sport can run $150 to $300 or more. If you don't book before sailing, you can visit the excursion desk onboard—usually open the day you arrive at each port—and book there, though popular activities may be sold out by then.
You are not required to book a cruise line excursion. You can explore a port on your own, hire a local taxi or guide, or book activities independently through websites like Viator or GetYourGuide. The trade-off is that you lose the may provide that you'll make it back to the ship on time; if you're late, the ship will leave without you.
Onboard activities included in your fare
Every cruise includes entertainment and activities throughout the day and evening. Most ships run a daily program—printed in your cabin or available on the ship's app—that lists everything happening that day. Morning options typically include fitness classes (yoga, Pilates, spinning), trivia contests, and poolside games. Afternoon activities might include cooking demonstrations, wine tastings, art auctions, dance lessons, or lectures on the destinations you're visiting.
Evening entertainment is the centerpiece of most cruises. Ships usually have two or three main theaters showing Broadway-style productions, comedy shows, or magic acts. There are also smaller venues with live music, karaoke, or themed parties. Dining experiences vary: most ships include a main dining room with assigned or flexible seating, a buffet, casual cafés, and specialty restaurants (some charge extra). Many ships also offer themed dinners—a pirate night, a 1980s party, or a formal night—where the dining room is decorated and the menu matches the theme.
Specialty activities like spa treatments, casino play, or premium dining do cost extra. A massage or facial runs $100 to $200. Specialty restaurants charge $15 to $40 per person on top of your fare. The casino operates like any land-based casino—you can gamble or straightforward watch.
What May weather means for your activities
May is shoulder season for most cruise destinations, which affects what you can comfortably do. In the Caribbean, May is warm and mostly dry, with water temperatures around 80°F—ideal for snorkeling, swimming, and water sports. Afternoon thunderstorms are common but usually brief. In the Mediterranean, May is warm and sunny, perfect for beach time and outdoor walking tours. Northern Europe and the Baltic are cool (50–60°F) but dry, with very long daylight hours—you'll have 16 to 18 hours of daylight, which means more time to explore ports.
Alaska cruises typically begin in mid-May, when glaciers are visible, wildlife is active, and the weather is cool but manageable (40–55°F). Earlier sailings in May may encounter ice or poor visibility. If you're sensitive to cold, bring layers and waterproof jackets for any northern itinerary.
How to choose excursions that match your interests and fitness level
Cruise lines rate excursions by physical difficulty: straightforward (walking tours, short bus rides), moderate (hiking, snorkeling, some climbing), and strenuous (full-day hikes, kayaking, zip-lining). Read the description carefully—it will tell you how much walking is involved, whether there are stairs or uneven terrain, and what fitness level is expected. If you have mobility concerns, ask the cruise line directly before booking; some excursions can be modified or alternatives suggested.
Think about what you actually want to do. If you're visiting a historic city, a guided walking tour with a local historian might be worth the cost. If you're in the Caribbean, snorkeling or a beach day might be more memorable than a shopping tour. If you're in Alaska, a glacier hike or wildlife viewing tour is often worth the premium price. Many people book one or two excursions per port and spend the rest of the time exploring on their own or relaxing onboard.
Ports that are best visited in May
May is ideal for Northern Europe and the Baltic. Ports like Copenhagen, Stockholm, Tallinn, and St. Petersburg are accessible and pleasant in May—the weather is cool but dry, and the long daylight means you can see a lot. Mediterranean ports (Barcelona, Rome, Athens, Venice) are warm and less crowded than July and August. Caribbean ports are warm and dry in May, though some cruise lines reduce Caribbean sailings in May because hurricane season is approaching (though major hurricanes are rare in May).
Alaska cruises begin in mid-May and run through September. May is the earliest you can see glaciers and wildlife reliably, though the weather is cool and some ports may have limited hours. If you're flexible, late May is better than early May for Alaska.
Frequently Asked Questions
Do I have to book shore excursions in advance, or can I wait until I'm on the ship?
You can do either. Booking in advance guarantees your spot and lets you plan your days. Booking onboard at the excursion desk is fine for less popular activities, but popular excursions—especially in small ports or adventure activities—often sell out. If you know you want a specific activity, book it before you sail.
What happens if I miss the ship because I was late getting back from an excursion?
If you booked a cruise line excursion and it runs late, the cruise line is responsible for getting you to the next port. If you booked independently or explored on your own and miss the ship, you'll have to pay to fly to the next port yourself. This is why many people choose cruise line excursions—the may provide matters.
Are there activities for kids on a May cruise?
Yes. Most cruise lines have kids' clubs with age-appropriate activities, supervised play areas, and evening programs. Excursions also often have family-friendly options like beach days, snorkeling, or guided city walks. Check the cruise line's website for what's available on your specific ship.
Can I do water sports like snorkeling or kayaking on a May cruise?
Yes, depending on your destination. Caribbean and Mediterranean ports offer snorkeling, paddleboarding, and kayaking in May. Water temperatures are warm enough in the Caribbean (around 80°F) but cool in Northern Europe and Alaska (50–60°F), so you may need a wetsuit. Check the excursion description for water temperature and what gear is provided.
What's the difference between a guided excursion and exploring a port on my own?
A guided excursion includes a local informed, transportation, and the may provide you'll make it back to the ship on time. Exploring on your own is cheaper and more flexible but requires you to navigate, plan your route, and manage your own timing. Many people do a mix: book one excursion per port and explore the rest of the time independently.
