I wish I could rate them a zero. I booked a Toronto hotel with them but the deposit was taken off my Visa in U.S. currency rather than Canadian. When I emailed to cancel they denied charging me in U.S. funds. I emailed back with my Visa statement as proof but never heard from them again. They have not confirmed cancellation nor refunded the deposit...
OMG, I just read other reviews and see that someone had odd charges on their Visa card after booking with these guys. Three days after using Hotelnparking a fraudulent $1200 was put through on my card, when I contacted my bank they cancelled the card and issued another one over the security breach. Beware!
