We've never done BBB at WDW, but we've done it on both the Fantasy and Dream. On the Fantasy, my daughter was the only child there for a time, but it did start to fill up as she got further along in her makeover. However, there are only 5-7 chairs in the boutique, so even when "full" it isn't too loud and crazy. On the Dream, all three of my kids did the Pirate's League makeover and they were the only ones in the boutique then too. On both occasions, we took many photos and videos on our own. There is no ship photographer there. At least on the Dream, however, they did have a "backdrop" where you could take a picture of your child once the makeover was complete (with your own camera). I don't recall if there was something similar on the Fantasy or not.
