I took my daughter to this boutique last year and she loved it just as much as, maybe more than, the Bibbity Bobbity Boutique! She loved Frozen everything though, but also it was waaaaay LESS crowded, a lot MORE one in one to the child(which I found to be more special, since there wasn't so much going on all the time and so many distractions that can be bothersome) and just as fun and glamorous as BBB. There is a goodie bag at the end, and the only real difference is that there's no upgrade option for princess pictures or special treatments for a price... here, everyone pays for the same pampering and makeovers and and lil princes or snowmen can get a cool transformation too for a lesser price than the princesses, and it's all done in half the time as BBB. But, this is a more CASUAL experience and the staff aren't going to be fairy godmothers or what have you, but they will be very accommodating and friendly
I have had my DD treated to both places in the past and I think she loved them both very much, but when I asked which one she'd rather do the next time she said the Elsa and Anna boutique That could change though It just depends who they want to be that day!
