Watch the small print. Tried to cancel my hotel reservations 24 hours in advance, as per hotel policy. However, hotel told me since I booked through booking.com I had to cancel through them but it would be "no problem" since I was canceling more than 24 hours ahead. Well, lo and behold booking.com had no options but to cancel electronically and they charged me the full cost of all four rooms booked because I didn't cancel 48 hours in advance. I attempted to call the customer service phone number listed but the call kept dropping and I could get no help. Moral of the story, I won't book through them again. Had I noticed they were out of the US I wouldn't have done business with them to start with.
