My little girl will be turning 5 this year so we're going for her birthday. As a surprise I booked for us to go to the boutique. The person I spoke to on the phone told me that her hair should stay in a couple days as long as we don't wash it. How true is this? Plus the one in magic kingdom is booked. They have a late appointment the day before we go to MK or the morning we go to MK (9:30). Which appointment should we take to make the most of our experience? BTW we are first timers. Another question I have is should I just buy a deluxe costume from the disney store vs buying one at the boutique? This is mainly because I don't know how great the quality of their dresses are. Do they take tips?
