We thought we were on Hilton's site and actually were on the CCI site masquerading as Hilton's site. We were up-charged a $52 fee for making a room reservation without knowing this or authorizing the charge. Simply a case of fraud perpetrated by them. Unfortunately our credit card company - Discover - was no help in disputing the charge. The additional issue is that we had to freeze our credit card account because CCI uses the card info [both # and 3 digit authorization code] to use or resell. Beware and stay away from CCI.
