Hi Mamaso, I finally got organized enough to get some photos up.
I think your GD will be OK if she can sit still. When we came, there were not a lot of girls there - it was about 9 am with the park opening at 8. The ladies were entertaining and playing with her throughout the process. I did ask that they don't pull her hair back so tight, so it might have taken longer. She did the Fantasy Princess hair (I think that's what it was called) with the tiara. The one with the extension might end up being too scratchy and hot, and the third one we did not care for. DD was already wearing her outfit, so she did not need to change (and I did not have to carry a set of clothing around the park lol). We picked a morning appt so that she can enjoy it the whole day.
They do have a booster on the seat:
They started with the hair, then a second person started the makeup and nails. They had given her the ring (color is different depending on the princess - Belle's was red).
We signed up for the Crown package (hair and nails), but added the purse and gloves, and the scepter separately. They put on the gloves and gave the scepter while the hair was being finished. Then they put the ring back on so it was on the outside.
I think they were pretty good about keeping DD occupied while the hair was being done.
We also got the photo package, and the photographer took pictures with two backgrounds in the studio.
We spent more than just the basic package, since we had the add-ons, but at least it was not as costly as getting the full package. It was well worth it!
