Like everyone says, (For now) make reservations long before you sail. Its a pain, but it is what it is.
Dynamic dining. We didn't wait once to get into any of the free restaurants. We never had a bad meal, and we are discerning diners. We are cruise people with over 26 cruises under our belts, on 5 different lines. This was the best food we ever had. The steaks were flawless. Don't go to chops and pay, when you can get a perfect steak for free. All 4 free restaurants were fine, do not worry about service or food. As a matter of fact just to test the new system we walked up to the Grande and pretended we didn't have reservations and we were sat within 5 minutes. Having different restaurants to go to was a blast, and its going to be hard for us to go back to traditional dining. We did not like the windjammer, and avoided it whenever we could. The choice and quality of food was mediocre at best. Don't go there between, 11:45 and 12:15. Most stations are closed transitioning between breakfast and lunch. The warm cookies were outstanding and we indulged more then we should have.
The ship. It was bright and new and polished. It felt like a mall to me though, and the shops were absurd. Expensive watches in everyone of them. They didn't even have a general store to buy things like batteries, or chap stick? The robot bar was fun once. The genuine pub was always empty. The music hall was fun with a police tribute band, karaoke, and game shows. The art around the ship was nice, and the elevators were just fine for us.
Perfectly fine. Horrible TV with limited stations to watch.
