This is your first cruise so no matter where you go, or what you do will be an amazing new experience. It's like the first love of your life - you'll never forget it. Saying that, I want to let you know that the Southern Caribbean itinerary is my favorite. The Radiance Class ships are beautiful. I love the open back dining in the Windjammer (the buffet) and the elevator with a view of the ocean as you're going up or down. I think you made a very good choice. Make sure you see the Crown and Anchor Loyalty ambassador and sign up to the Crown and Anchor Society. It's free and you will get a coupon book if you sail with Royal Caribbean again.
