My husband was sent to Hotel Power through the Trivago website. Hotel Power took our money but never made the reservation. I see in the reviews that this has happened to many other people. My husband sat for 3 hours in the hotel lobby calling Trivago and Hotel Power to try and straighten this out. His calls were not returned and finally, shortly after 5pm, he was told the Trivago office was closed! No one has ever gotten back to him. Trivago is responsible for sending people to Hotel Power, a company that obviously is scamming people. The Internet has many complaints similar to ours about Trivago and Hotel Power. From now on we'll book directly with the hotel. At least that way we'll know we actually have a reservation.
