My sister and i are sailing on the Caribean Princess in September. She's 21 and I'm 25. I know she is really looking forward to the night life and partying. Is the crowd generally younger,older or just a mix? Plus we are on the Emerald deck in an oceanview partially obstructed. Can you really see anything??? and is that deck kind of a low deck?? Thanks for the help. We are so excited it!!!!
