I am having the same problem!!

For me...it just isn't feasible to make multiple shirts for each person on the trip just because I won't have enough room to pack them!! (My sister's family is coming from Michigan so we are meeting them down there)
So this is what I am doing...1 or 2 tee shirts for each person in our group, 1 pillowcase for each kid (and maybe the adults, lol) for autographs (the kids are a bit older, range in age from 10 - 16) and then making window clings out of all the other fabulous DISigns that I love from these boards. We are staying in two hotel rooms so I figure there will be plenty of window space to decorate! Oh and I am also making pressed penny tubes, tip envelopes and candy envelopes!
I am also thinking about possibly doing a tote bag for each person and fill it with their goodies.
Hope this helps,
Jes
