We started collecting shot glasses before we had a family. They are nice to look at, don't take up lots of space, and for the most part, they are virtually indestructible. We have a handful of Disney glasses, but we only get ones that are truly unique. Sorry, no pics.
MK - ordinary shot glass with elaborate fireworks printed around an image of the castle
Epcot - flags of all the World Showcase nations are printed on the inside of the glass. It looks really neat if you look through the side.
DHS - Rockin' Roller Coaster -- there's a glass guitar protruding out the sides of the shot glass.
AK - Expedition Everest glass, covered with bits and pieces of Tibetan theming, with big claw-marks scratched in the side.
Disney's California Adventure - a Tower of Terror shot glass that looks like a mini huricane glass, with the HTH logo inside.
Disneyland Paris - Very classy, black-and-white Mickey image on a tall frosted shot glass.
Unfortunately, we never found any unique shot glasses at Disneyland, Tokyo Disneyland or Tokyo Disney Sea.
Our daughter is learning to count, and she loves to count the Mickey's in our shot glass display case.
My non-Disney favorites:
Universal Islands of Adventure - Dueling Dragons - Pewter dragon mounted on top of an upside-down shot glass. It looks really cool. To use the shot glass, it stands on the dragon's nose and wing-tips.
Holiday World - A mini three-masted ship mounted inside the shot glass, commemorating their big wooden roller coaster: The Voyage. Not very useful (or easy to clean), but very impressive to look at.
