My wonderful parents sent me a bunch of old LV room keys (real keys). Half of them have the hotel imprinted on them, but it have around 5 that I cannot find through my research, which hotel they belonged to. They have the mailbox number on them but no hotel name (remember those instructions to drop the key in the mailbox and the key would be returned to the p.o. Box?). So to make a short story long, will there be folks at the convention who know keys?
