Ports of Call
Orlando (Port Canaveral), Florida - As the home of Kennedy Space Center, Cape Canaveral is the launching point for all-out adventure in Central Florida. Since your round-trip cruise begins and ends here, you have the perfect opportunity to extend your vacation and explore the region at your own pace.
Orlando’s legendary theme parks, including Walt Disney World, Universal Orlando Resort, and SeaWorld, are just an hour away, making pre- or post-cruise visits both practical and rewarding. Beyond the parks, you’ll find charming coastal towns, family-friendly beaches, and unique local attractions. Kayak with manatees in the Banana River Lagoon, zip line over gators at the Brevard Zoo, or explore the arts and culture of Park Avenue and the Orange County Regional History Museum.
Whether you choose to arrive early or linger after your cruise, Port Canaveral gives you access to some of Florida’s most unforgettable experiences—well beyond what’s possible during a single port of call.
Coco Cay, Bahamas - Located in the middle of the Caribbean's bright blue water lies the secluded island of CocoCay. With its white-sand beaches and spectacular surroundings, CocoCay is a wonderland of adventure. Reserved exclusively for Royal Caribbean guests, this tropical paradise has recently been updated with new aquatic facilities, nature trails and a ton of great places to just sit back, relax and enjoy a tropical drink.

San Juan, Puerto Rico - The vibrant capital of Puerto Rico, San Juan offers something for every traveler — world-famous beaches with crystal clear waters, incredible cuisine, rugged natural beauty and a rich history that goes back 500 years. With its ancient fortresses and colorful colonial-era buildings, San Juan makes it easy to feel as though you’ve slipped into the past. Life moves at a slower pace along the sunny cobblestone streets of Old San Juan, and salsa beats seem to waft perpetually from open windows. If you’re craving a hike, head to El Yunque National Forest. And if you’re more in the mood to unwind, set your sights on the beautiful shores of Isla Verde or El Condado. Mealtime is also an adventure, with so many delicious options to try — from mofongo and pastelon to chillo frito and alcapurrias. Pair every bite with a piña colada — Puerto Rico’s national drink.
Philipsburg, St. Maarten - The capital of the Dutch side of St. Maarten is the town of Philipsburg, though St. Maarten is an island with two distinct sides. To the north is the French side, whose capital is Marigot, while Philipsburg sits on the southern part of the island. When exploring on cruises that go to St. Maarten, it’s important to visit both sides to understand their customs and heritage.
You’ll quickly be charmed by all sides of the island. Of course, this Caribbean island is best known for its beaches, like Maho Beach or Great Bay Beach, one of the area’s best snorkeling spots. Sample local seafood or rum during your time in port, which have become symbols of St. Maarten life. There’s just enough to fill the day here, especially if you hop between the French and Dutch beaches.
