Our party included two 18 yr old boys and two 22 yr old girls. Although we all love to have fun, we are not the easiest group to please - isn't everyone a little high maintenance? With that said, I can honestly say that everything was absolutely amazing. We did our best to see most of the ship, attend the shows, soak up the sun, and have a drink in each of the 13 bars (only got to 10).
We have read some complaints about the ship: room size and configuration, crowded elevators, and lack of seating at the Windjammer. Guess if we had any complaints - these would be them. However, we only went to the Windjammer twice because there were way too many great places to eat on the ship; we took the stairs whenever we could (to work off some of that great food); and we didn't spend too much time in the room.
Tip #1: Our room was on the back of the ship. We overlooked the Boardwalk and the ocean from the back. Highly recommend this location. We watched water shows, movies, etc. from our balcony.
Very quiet. Great view! Could watch shows from balcony (movies, water shows) and could also see Boardwalk and the ocean! Great location. Lots of walking, but well worth it.
