First timer here. I knew I was overpaing, but still a hell of a deal. I got the Hilton next week for $150us. I Should have started around $100 eh? I had no idea about these sites a month ago, I booked the Sheraton straight off Expedia for like $270! thanks, will do better next time ;) Question then. Is it be possible to Cancell the Sheraton (since it was full price) and rebook through here again?
