And if the hotels will want to accept only fiat money? Crypto currency is not so common.
Tetarise accept payments in cryptocurrencies and in fiat. If hotels need fiat, so owners of the aparments and villas will accept cryptocurrency with a big pleasure, cause this type of payment carries with it the absence of taxes. It's also kind of money saving. I would lease apartments for crypto and then would spend these money for travelling.
Payment with cryptocurrency has a lot of advantages. Maybe hotels don't understand it now, but when the token will rise up they will see.

Sorry, but I don't understand what will happen with the hotels when token will rise up?

When the token will rise up, hotels will start to accept and save it, cause ammount of tokens is limited and the number of bookings is not.
So as more tokens will be saved and not withdraw to fiat, as faster the token will price will grow.
