I'm in the same boat! My DD4 absolutely does NOT want her hair done, but she wants the make-up and nails. I also have DD6, who is getting her hair done, so we'll be there anyway. I thought about canceling DD4's appointment and just buying her a crown and makeup kit, but I'd feel awful if she changes her mind once we get there and they can't fit her in. So, yep, I'm probably going to pay $50 for make-up and pixie dust.

Call me crazy, but it's vacation, and I want my little princess to be happy.
