We both work in Child care and when we go to WDW we like to bing back a little something for the kids...we have got Mickey stickers, and some cool mickey head straws. We didn't have to pay for either of them, and they supplied us with enough for both of our centres (a total of 100 kids). They were awesome about giving us things. Some things I bring back for friends are named keychains, and pens. We usually bring back some type of food thing for our co-workers (eg. chocolate covered pretzels, salt water taffy, cookies etc).
Good luck!
