Are they easy to find in the parks? DD is getting a doll for Christmas this year, and I wanted to pick up the Minnie costume for her too. If I can't get it down there though, I'll probably need to order it before we go, since we won't be home until late on the 20th. I'd rather not have to pay overnight shipping. Also, do they have other outfits there that aren't listed on the Disney Store site? I was hoping for a Cinderella costume. Thanks!
