Not to sound mean or anything, (and I apologize if I do,) but I think its kinda tacky to pass out souvineers of "your" vacation to every kid in the classroom. most of them don't care if you went to Disney World or not, and bringing them a cheap little reminder of "your" trip seems like you are bragging or something.
I'm sorry to sound so mean about it but thats how I feel about passing out souvineers to an entire classroom or neighborhood full of kids who probably don't care where you went anyways.
I bet those kids would appreciate an Ice Cream or pizza party FAR BETTER than some trinket souvineer of "YOUR" vacation.
