This isn't hotel-specific but my tip is the following: Assume your smartphone gets lost/broken/stolen or your wallet gets lost/stolen (or a credit card gets flagged for fraud). Do you know where you're actually staying? Do you have a copy of your itinerary more generally? Do you have backup credit cards and IDs?

I'm not super-fanatical about having printed maps etc. in a familiar city but I try to have backup of everything especially traveling internationally.

For example, a few years back, I somehow managed to lose my drivers license between the limo and the terminal door. It was a short trip and I hadn't bothered to bring my backup travel portfolio. Shockingly, TSA (at least at the time) let me get on the flight after some enhanced screening. But I had a heck of a time getting the hotel--which wasn't one of my usual chains--to let me get a room.
