One of the main reasons lots of people hold credit cards is the fact that they can use them anywhere in any currency.
With the low transaction fees and easy usage, bitcoin could take over a huge portion of the wealth spent at hotels and on holidays.
Seeing the amounts of hotels and resorts that accept bitcoin on
coinmap there is definitely room for growth there. The fluctuations in price are high at the moment, but obviously the same can be said for fiat currencies in some countries. (if you lose 3% in fees/conversions and 4% to currency fluctuations no one bats an eye, but if...)
In addition there is also a market for anonymity in hotel visits. Let's say you are taking your mistress out on a trip and book a hotel. You can't pay by credit because your wife checks the bills. You can pay in cash, but do you want that amount of cash on you? Bitcoin could solve this problem. Certainly the Chinese are not the only ones creating 'black wallets' to spend abroad.
I wonder if any of the hotel chains could be persuaded to accept coins and what the impact would be on the bitcoin economy. No chargebacks also means they have their money every time.
