This wasn't done for me, but I did this, and I had to share
Last month, nearing the end of the DL trip for my friend and I, we realized we had some unopened fruit cups that my mom had given us for the trip, so I found a family that was headed back to their room from the pool area, and explained things, and they were happy to receive them.
Second thing, checkout day, I gave some unsuspecting couple a couple of guidebooks I had (Birnbaum's and Frommer's), since I wasn't going to be back for a while, and I thought someone could get more use out of them instead of lugging them back home, and having them collect dust.
There are my stories!!
