So...who wants to talk Tinkerbell gifts?

As I understand ... tinkerbell gifts (also called Mickey Gifts) are little items you bring with you and leave out for your kiddos either at the beginning of the day or the end of the day to enhance their Disney experience. (Also - could be used to encourage good behavior, save on souvenirs purchased on site, etc)...

What have you done like this? Any awesome ideas?

Or what are you planning? Would love to brain storm off others here!
