We did BBB on the MV- and had an incredibly wonderful experience. Booking wasn't open online, but I went there immediately upon boarding (boarding #4) and reserved a late afternoon spot for my 7 yr old daughter on formal night and my 10 year old daughter for pirate night. Our "fairy godmother in training" Katya- was so great. It was almost a full hour of intense attention. I had brought a new dress from the Disney store to surprise my daughter- and she did the make-over/hair/nails option which was about $59.00. I think it was some of the best value-for-money spent on the cruise- really special. My older daughter got the same treament for pirate night- she also had her costume- but got a make-over (Empress-about $35)- nails, a medallion,sword- and just had a really great time. I have never chosen to do this in the parks but would do it again on the Fantasy in a heart beat!
