This is actually where Bitcoin *sucks* for spenders. My advice would be not to pay the BTC until you actually arrive at the venue but quite likely the provider will not want to do that (and you won't know if they will even then have a suitable room for you).
So assuming they won't agree to an escrow and you don't want to trust them I'd have to say "use a credit card" or "paypal" (at least those can be reversed).
Also - best to get a "pick up" from the airport as the "so-called taxis" are the biggest ripoff there (you will get burned with that - having been there myself I know).
Bitcoin will stop sucking in regards to spenders once we finally get fully functioning decentralized 0 trust escrows. We need this really soon so we can stop scammers. Soon being a escrow will be yet another automated job thanks to technology.
