very interesting. my first RR 36 cards were reported exchanged. 2 people did not log in or out. as requested. the RR was rerouted for no aparent reason except personal. 2 cards were added. 3 card were returned that have no connection to a casino. pictured in scan. the card that says las vegas hilton would like more information. as have 5 different cards from there and they are the 1 3/4 cards not the 2 1/8. how do they fit the door slots?. now if we can find out what happened to ROOM KEY RR # 2. i can understand the anxious moments from the start to the end. with this small RR it took 6 weeks. good luck with more than 10.
