NO charge to use the safe, we used it many times, wished we had known about the ATM thing. Our teens lost their card a couple of times(we found them all in the room later) and when they get a new card, it doesn't work the safe. So we had maintenance come down twice to unlock it for us, only maintenance can do this from what we were told/saw. Our room steward could not. This first time was because it was still locked from before or something, only once was our fault. When you have alot of people of different ages, a generic card would be best. We had lots of times when someone needed something out of the safe but the right person wasn't around.
