Proceed with extreme caution
I stumbled across what seemed to be a great deal on trivago for a 6 night stay in a hotel in Ibiza, and proceeded to book with this incompetent "company". They were very quick enough to take my money and send their reservation "confirmation" and hotel voucher (?!?).
I was very skeptical about the whole process having read their policies and way they operate, so after the advised 24-48 hour waiting period for the hotel to receive the reservation, I rang the hotel directly to check.
The hotel informed me that there was neither a reservation on my name, nor on the dates that I had booked for. I contacted the hotel again the following week and got the same response. I then called cancelon who assured me they would contact their "third party sellers" (alarm bells sounded when I heard that), and they would contact the hotel with my reservation number. I again received a new confirmation from cancelon, waited a week, rang the hotel and surprise surprise, no reservation. I went through this whole process once again to give them another chance before admitting to myself that this is just a very poorly executed and suspicious scheme, and I would probably end up showing up at the hotel with no reservation or back up if I trusted them. I thus cancelled and requested a refund of the money - to their credit (?), I received my money back a few days later and breathed a sigh of relief.
This doesn't offset the emotional trauma of this whole experience, the time and money spent on calls to Spain, and the fact that this process took roughly a month to sort out. In the meantime the hotels at my holiday destination had shot up in price considerably, so I have had to pay a lot more than I had originally budgeted. Warning to you all to not put your faith in this company, no matter how good the deal looks - pay a little bit extra and book through more reliable booking websites or the hotel directly to avoid what I and many others have gone through.
Shame on you cancelon, and shame on trivago for listing them as a partner site. I will not be using either service again.
