Hi we had it done for my daughters birthday last week. I originally emailed them for prices and how to book, they implied you could book in advance over the phone but this is not the case.
You can only book once you are there, you book in the
Disneyland Hotel boutique (shop) on the first floor. The prices they sent me were also incorrect but luckily I took a copy of the email and they did honour them. To be honest I didn't pay much attention to the new ones (not much help am I

) BUT from memory I *think* you can only do the complete package now - ie hair, make up, dress, accessories and photo, and I *think* the Tiana one is 135 Euros, best thing to do is email them or phone (they speak English).
The makeover itself takes place in the Disneyland Hotel on the first floor and I have to say it was one amazing experience, we had the Tiana package which inluded hair, make up, tiara and photo. The staff were really lovely and made my daughter feel really special (it was her birthday too).
I've got some lovely pics but our pc has died and the scanner is attached to it, I might try and take a photo of them. Once I'm sorted will post pics.
