Hi there, just wanted to put my two sense in as someone who has worked as a "Fairy Godmother in Training." One question I would have is how tolerant your daughter is on having her hair tight. These hairstyles tend to get pulled tightly in order to stay as long as possible. I have had both circumstances where kids have wanted to pull it out within a couple hours because it was too tight for them but also have had parents see me in the parks later in their week and tell me the hairstyle is still going strong at day 4(the fairy tale hairstyle mostly) and those kids were able to sleep in it for days. Another question is how fine is your daughter's hair and how old is she? If she is school aged (6-10) has a full head of hair it'll last longer than wispy hair of a late toddler/preschool aged child. Another question is do you plan on riding splash mountain? If so I'd ride before the appointment! Yet another factor is the hairstyle itself. Like I said the fairytale can last for days on the right person but the ones with the fake extension can mess up a bit more easily. Other than that, the hairstyles will last a good amount of time as long as she doesn't pull at it. I would watch how the Fairy Godmother teases and places the fake extensions if that's the hairstyle she picks, that way you can do touch ups on your own if she messes it up and gets upset. It also helps to watch when it comes to taking the hairstyle out! You'll know what's been pinned, where the elastics are, etc. So I guess my advice is unless she has really wispy hair, is bothered by having her hair tight, or plans on going on splash mountain multiple times you can pretty much plan it for anytime

Enjoy!!!
