We did the same itinerary on Freedom and loved it. Don't miss the parade that starts late on the first evening, down the Promenade. If you stand close to the pub you will have the best view. Don't miss the Ice shows, even if you don't care for Ice skating, they are spectacular. We loved the main Promenade, lots of wow factor but also lots of walking....it is a HUGE ship.
I could sit and watch the Flowrider all day, that was great fun. Try the cantilevered hot tubs, you are really hanging out over the ocean..
I always think the private island days are the best of the cruise, no rushing for excursions, no shopping or taxis to get, just relaxation and fun. You picked a wonderful ship for your first cruise....
Be sure and study your 'Cruise Compass' daily, this is a bulletin of all activities and it is delivered to your room nightly. Highlight the things that interest you or you will find there is so much listed you lose track of items you wanted to attend.
