I love all of the ideas on these threads! Here are some more:
* if you do Tinkerbell gifts, sprinkle a little glitter around them for pixie dust
* provide stacks of 2 quarters and 1 penny for the penny press machines - these fit great in a mini m&m tube and kids love to search out the machines and collect all the different images -- there must be hundreds!
* provide disposable cameras to the kids to get their perspective of the trip
* make customized autograph books to collect signatures of their favorite characters. check out the Creative DISign board for some inspiration -- many talented folks there share their templates and will also customize for you. Character meals are great fun and very efficient for collecting autographs. There are also some passport books you can print out/make for extra World Showcase fun (also, do the Kidcot funstops as pp mentioned).
* you can also check out the Creative DISign board for t-shirt iron-ons - families in matching t-shirts end up having some really nice group photos.
* consider pin trading
* buy'em at the dollar store and pass out glow sunglasses/bracelets/necklaces/sticks to your crew on evening excursions.
* have everyone take pictures in the different hats at the countries around world showcase and all over WDW. I have never seen so many spectacular hats.
* take photos of the Beverly taste test at Club Cool in Epcot
* If you are going when
MNSSHP,
MVMCP or P&P parties are going on, consider attending
* take advantage of every photopass moment
Have a great trip and happy planning.
