Been to Vegas many times but never used anything but the safe in the room. Seems like I have read however about other safe rental options. Will be there later this year on what is mostly a Grand Canyon trip but with days in Vegas before and after we go to the canyon. Would just as soon not take my gambling bankroll to the Grand Canyon - and my wife would probably prefer to leave some jewelry as well. Is it possible to rent a box at a strip hotel to store valuables for a few days until we return to Vegas? Will likely be staying at a CET property - most likely Bally's. Any input on which properties might have this option would be helpful? Do you get access through the concierge or do you go to the casino cage?
