Anthem is my favorite ship so far. We loved it but I understand what you read. There were a lot of first time cruisers on her and a lot of people who seemed to be expecting more than what they paid for. Since it leaves a cold port the casino was packed most nights and not very big. I mean there were people arguing over machines. This was worst when we first left and at the end when we weren't in warm water.
We also met some awesome people and tried to get machines close to the same people and cheer each other on. I missed the shows and could kick myself but hubby really likes the casino. The kids loved it. It is so nice to drive to port and board verses flying.
One of our Anthem cruises got canceled this year but we are sailing her for Christmas and I'm super excited to sail on her again.
We are in our 50s and Diamond, should be Diamond + except for canceled cruises.
