Ok, I'm feeling the need to chime in again. First off, someone mentioned that if BBB becomes kids only, than there should be a restaurant that bans kids...that's just dumb. You don't need kids to enjoy Disney, me and DH had some great kidless trips there...but it is primarily a family destination and it is not in their best interests to alienate kids from places. You can argue me all you want on this point, but Disney's main demographics are kids and families so they aren't going to put anything in the parks that is less than kiddie accomodating and that's how it should be. If you don't like kids, than maybe Disney isn't the best place to vacation.
Also, every adult who thinks it's their right to get their hair done at BBB really needs to get over themselves. If you want to do it, that's fine, I don't care, however, to say that you deserve it more than a child is just wrong. This is a KIDDIE boutique. While Disney will let in anyone willing to pay money, it still does not lessen the fact that it was created with little girls in mind. If you are fine taking the spot of a little girl whose mother didn't realize that reservations were needed, than those are your values. However, it is very selfish to say that you deserve to get your hair done at a KIDDIE boutique more than a KID because you knew you had to make a reservation in advance, when the kid's mother did not.
