You can get pixie-dusted by the CMs in castle couture. Many CMs give out stickers to the kids. I think it's called the pirates adventure in Adventureland--you complete a scavenger hunt with map and get FPs to POC. The Ghirardelli in DS gives out a sample square of chocolate. There is a card game called Sorcerers of Magic Kingdom, you can get your first pack of cards at the fire station on main street. Paper maps are at the entrance of each park and are a fun way to remember to trip. Ice water is free at each QS.
I hope this helps!
