That's amazing news my sister who's soon to visit Las Vegas will ask her to try this out, if it really works. I feel this is a master stroke, cause people often loose all thier money while betting and are left on the streets, but thanks to these hotels, they at least will be safe. But one question here, let's say Mr, x a newbie to Bitcoin goes gambles and then decides to pay via btc. But the transaction is not confirmed and he is not allowed, post that day transactions are confirmed, what happens then does he get refund, this is something that will be an issue. Otherwise, I feel it's really nice.
You are absolutely right. There is a way to counter this. Because, in most cases, customers have to give their credit card number to book the hotel. It will be charged only when the bitcoin is not confirmed. Even then, hotels must be a branded one with good customer support otherwise there is always a hassle.
