Sorry to hear of your friend Kelly. I'm sure she would want you to have a good time on this cruise.
I spoke with Ann today with Cruisingforlove.com and she said there were quite a few people in their 30s and 40s booking. I think I can speak for SheDaisy (my roomie) and myself and say that we are looking forward to this experience tremendously. I just hope I can last until May! I'm also looking forward to putting a face with all these cyber names and meeting lots of new, fun, people.
