I've sailed RCCL and HAL, 3 on each line. I usually prefer HAL for just the family as DD gets attention and we can just relax. I am not sure if I can go back to the big ships or not.
I think many aspects of this ship look great, just the size scares me (as well as the number of other people on board). The name is fantastic.
Oh well, we are looking for Western Caribbean in April 2009 as our next cruise.
