I recently listed my property with booking.com, but so far people just book and never show up since a credit card is no need it to reserve. I have my property list it with other sites too, but the issue is that if a guest book with b.com then my calendar get all screw up. I end up losing money because the guests from the other sites cant't book due to the calendar been block by b.com. It's frustrating. Can somebody give me advice on your experiences? What do you suggest I should do? B.com said that I need to build a good relationship with them before they can trust me with credit card information for each guest. Why? I have a 5 stars rating with the other sites, isn't that enough?
