I love all of these ideas!
I started collecting snowglobes when we first started going to the parks in '99. There were always so many to choose from, and they were all beautifully ornate, with such colorful details! I always had a difficult time of just sticking to one per trip! I remember when the "snow globe" parade first started, they sold snow globes that matched each float, and my DH surprised me and bought every one of them for my collection!! But, lately we've had a hard time finding any, and the ones we do find are much smaller and don't do anything special - like play music or light up. So, I wish they'd bring those back.
They also used to sell miniature ride vehicles from some of the rides that have the Disney characters riding in them. We have Mickey and the Yeti riding in a Matterhorn bobsled, Buzz Lightyear in a Space Ranger Spin vehicle, Mickey and Goofy riding with a ghost in a DoomBuggy, Goofy and a pirate in a boat from PotC, Peter Pan in a sailboat, Braer Bear and Braer Rabbit riding in a log, and Dumbo from the Dumbo ride. It would be fun to get some more of those!
