i know that we can't tip but when we went to CTI four years ago, everybody treated us sooo well. i have read about people bringing school supplies, etc. what have you brought? how did you give it? leave it on your last night? hand deliver? just curious - i would love to do something little for the workers. nothing too expensive or heavy :-) we are trying to pack one bag to check total then each have a carry on. i am putting an extra bag in our bag in case we need to check two on the way home - i want to get some alcohol and a wood carving.
