Review of Guestreservations
They take your money without your consent. They let you fill out credit card details, then mid-way through the booking process suddenly the price is waayyyyyy higher, but even if you never click on okay or finish the booking process in any other way, and close the web page, suddenly they will have taken money out of your credit card account. And then they cannot be reached. To the Guest Reservations founders or anyone who sold their soul by working there: bad karma will bite you in the a$$... just wait and see.
