Really stupid hotel, I booked the hotel for my friend with my credit card and they sent us a link to do the online check-in in order to get the code to access the key. The link requested the credit card to complete the online check in, which is my friend did with his credit card. then the hotel charged my credit card as well, I called the hotel, they were unfriendly and insist say no, I told them to check….after a couple of times, they found I was right…if you don’t know, or understand your online system why you use it????
