My husband and I had never been on a cruise until last March. We'd never been to a spa either, so we decided to try the Surial Bath on the 4-day Wonder. What a disappointment. The big shower didn't work, most of the facial spouts didn't work. I had to get dress go out and tell an attendant that the big shower didn't work, all she said was sorry. Then when we decided to try the facial and it didn't work - I did not go back out. She didn't even offer to put us in another room or anything. So now my husband doesn't want to waste anymore money on the spas.
That doesn't mean you won't have a good time and have everything work fine.
