S.H.
We did Bippity Boppity Boutique with a friend in April 2007 for her 5th birthday. My youngest daughter, who was a three year old at the time, was invited and at the last minute, my then eight year old filled in for a "no-show".
They both loved it immensely. My oldest, at the time being 8, wasn't really a princess-stalker to the degree of my youngest and her friend, but she loves Tinkerbell. They made her up as Tink and my youngest as Sleeping Beauty. They performed miracles with the hair and makeup! Amazing! Bring your camera for lots and lots of pixs. The lighting in there is bad - I think on purpose to make our pixs look yucky compared to the Disney ones that they will take and offer. I did buy some of theirs as mine weren't as nice. Pricey but worth it!
Everywhere we went thereafter at Downtown Disney - cast members treated the girls like they were royalty. They bobbed their heads and curtsied and said "hello princess" ... it was priceless!
We ate at Rainforest too and they loved it. The staff, of course, fawned all over the girls and made such big deals .... your little 5 year old will love it. It took my kids a week for their egos to come back down to earth!
Enjoy!
