We came in today to Sedona, Az after booking with Trivago who sold us out to a third party Elvoline who changed our booking date without authorization! We got in and was for the wrong date which they admitted THEY CHANGED. Elvoline refused to work with us by changing the date back to our date or refund. Elvoline wouldn't even give us the # to Trivago! Had to make a dispute with my bank. After 45 min Elvoline admitted they lied and weren't third party to Trivago at all but had our info and would not give us the name of the third party. They said they were from Hungary and had no supervisor. All in all was a nightmare! Do yourself a favor and never use Trivago because they will sell you out to second and third party not in the USA and change change your booking dates!
