Aerogirl, good luck re / your group cruise. I been there an did that ONE time and after that, that was enough for me. There's always some who waffle-- maybe we can go and maybe not--we'll let you know-- can't get off work then, can we go the next month, etc., etc., etc.
I think you would probably like the Dream but as always, some would and some would not. Good luck in whatever you decide.
I think you hit the nail on the head when you aid you would get the prices, and let them know when you were booking and leave the rest to them--if they want to go, they'll go--if it's all talk, you'll soon find out.
I think the Dream is fine, but that's just my opinion.
Good luck and happy sailing.
