First of all, the ship is everything it is advertised to be but if you have issues with sensory overload this is definitely not the ship for you. We are not new to cruising (30+) but never on this size ship. We chose this ship because of the appeal to all age groups.
Embarkation was easy, debark was a little more hectic.
There were 18 of us that were celebrating a 50th wedding anniversary and birthdays with a varied age group beginning at 7 years old. We loved the boardwalk aft balconies as we could see the Aqua shows, rock climbing and the ocean. We chose to open all of the balconies so we could interact with one another.
Aft Boardwalk balcony cabins are a great location but they are small. Good for 2, maybe 3 but 4 not so much.
