I did the Tinkerbell gifts for my DD two years ago. She was turning 7 during our trip. I found small Disney theme things at Dollar Tree and other stores and left them next to her bed with a little note from Tinkerbell that I printed on the computer before we left home. They even coordinated with what we were doing each day. If we were going to MGM, it said something about not to miss Beauty and the Beast show, etc..
Some of the things I gave her were, lip gloss, candy, notebooks, pencils, and stickers. She loved it! We are going again for her birthday this year. She asked me if I thought Tinkerbell would leave her anything again. I wasn't planning on doing it this time, because she is turning 9, but maybe I will.
