The first hour aboard is spent uttering the same words, WOW and WHOA. This is an incredible engineering feat.
The front of the ship includes the dining room (decks 3, 4, 5), casino (deck 4), and on deck 6 the Aqua theatre and boardwalk. Above the completely open air boardwalk are the balcony cabins starting at deck 7, up to deck 14). If you are travelling with kids you may prefer this side of the ship. It includes the donut shop and seven types of hot dogs stand (both free). Paid shops include a candy shop, ice cream shop, and a build a pet experience for young children ($32.99), which was a very good value. Deck 17 has access to the flowrider, zip line, sports court, and mini golf.
The rear of the ship is the open air Central Park on deck 8, which includes a Britto art gallery and most of the (paid) restaurants. The rooms on deck 9 overlook and have large windows and are a great value. Decks 10 thru 14 are the inside balcony rooms.
