There's a post a few threads down discussing welcome gifts from Mickey. We are planning on making a welcome gift ourselves and 'planting' it on her bed at the hotel secretly before she gets to the room. We are hitting Walmart tomorrow in fact to see what we can get before attempting the
Disney Store. Looking for Disney PJs and snacks. DH recently went to a business conference and brought home all the Mickey soaps, shampoos and lotions from the hotel room (we're off site so we won't get that).
We also like to collect things on our trip and make a scrapbook when we get home. We call them 'instant souveniers' because they are quick and free. Stuff like a drink coasters from the restaurants we eat at, ticket stubs, menus, anything from rooms, maps, flyers, unused fastpasses, etc. The fun while you are there is in the 'hunt' for Instant Souveniers! Technically it has to be free, but sometimes we will make an exception for something you have to buy. Then we match them up to photos of that place in our photo album/scrapbook. Then we get to relive the trip over and over and the 'instant souveniers' really make it special.
Also....maybe starting the trip with a character meal would get her into the spirit. We are planning three character meals - first day, one in the middle and we are hoping to do Cindy's breakfast on the last day, so keep your fingers crossed for us that I can get the ressie!
Enjoy, and be sure to watch the 'magic' on her face - it's the best gift of all.
