The casino was pretty typical cruise chip casino. I did like that it was easy to grab comped drinks from the casino bar. I actually liked the food. One of the big complaints from people is that because it is European service, it is a very unhurried pace.
I was with myself sister (and survived - who knew that was possible?) and we just had an ocean view room. It was small but fine, and I never felt that I wished I was in Yacht Club. That said, YC does seem to get rave reviews, so it might be worth it to you. However, I LOVE Aft staterooms because sitting on the balcony watching the wake is amazingly peaceful.
I am getting excited about going back on her, so ask as many questions as you can think of!! It makes me happy
