This is a beautiful ship, and I did my homework before going. We bought a spa package and loved it. I believe that ALL the children in America got out of school right before we left, because the sheer number of children was astounding. It mostly caused problems in the buffet or hallways.
I felt the slot machines were very tight, and never saw anyone get a hand pay during the week. That being said, a Cruise is always what you make it- and ours was fun.
Gorgeous ship, well-appointed Jr Suite (love the bathrobes!), so many good food options/ restaurants, plenty of onboard entertainment, and there are 2 casinos on board. The non-smoking casino is small and cosy. The main casino has many table and machine games. Both were busy and it was not easy getting on a machine to play, unless you go really early or really late.
We paid for specialty dining at Hooked and Izumi Hibachi. Both experiences were stellar!
I also enjoyed the peace and quiet of the Crown Lounge, not to mention their coffee machine.
Great experience sailing on Wonder of the Seas and I would love to sail on her again.
