I am 35 and took this cruise with some family members (12 of us in all). We live in LA and drove to San Diego the night before the cruise and stayed at the US Grant - lovely hotel!
We arrived for embarkation at around 12:30. The staff at check in were incredibly rude and abrupt and acted like they were being tortured by working there. Between the 12 of us we checked in with 4 separate people and we all had the same experience - not a very good welcome to your cruise! It was about 1:15 by the time we were on board and we were completely aggravated and frustrated by the way we were treated.
The ship is nice but nothing special - I am used to Princess and the atrium, etc. When we walked on board it was anti-climactic. The 3-story atrium is ho-hum and small with low ceilings. I felt that the ship is very chopped up - lots of small spaces everywhere - it didn't seem open and free-flowing.
