On my recent trip to WDW I was able to catch a glimpse of the new "snowglobe" floats during the taping of a commercial for the celebration. My pictures haven't been developed yet, but Hope Maxwell was there as well and was kind enough to post her pics. Here's the link to the images of several of the floats that we'll be seeing come this fall.
