As I understand you will pay when we give the hotel and staying people info , right? After then, you will get your money via BTC.
Noooooo.... bookings can be cancelled!
If anyone is going to use this service promoted by a throwaway account, send to an escrow that will
hold your money until your vacation is over.
If the OP is not willing to do this, then I would suggest not working with him - too risky that he is obtaining these vacations via illegal methods that will be discovered eventually - you'll be out a vacation but he'll still have your coins.
