A week before my wife and I arrived I booked and paid for, in advance, 3 nights in Enid. We booked the king studio suite with sofa bed. When we arrived, we checked in, got our key cards and went to our room. The room was not the room we booked, but a much smaller room with two beds. We hauled our luggage back to the lobby and told the person there, a young woman, that we were given the wrong room. I pulled out my phone and showed the pre-paid booking for the king suite. An older woman with longish hair came out and said that all the king suites were booked and we had to be moved into the smaller, cheaper room. This was unacceptable. Since when is it Hampton Inn policy to move a prepaid booking into a smaller, cheaper room without so much as a word in advance? I made it clear this was not acceptable and asked for a corporate number. The older lady, huffing and puffing and complaining about how hard it was to keep bookings straight (Is this a proper conversation to have with a guest, Hampton Inn?) and finally got us the room we booked and pre-paid for. While doing this, the woman made the offhand remark that this particular room's rates were higher that weekend, which leads me to believe that she moved us into the smaller room so she could charge the higher price for walk-ins. Once in the room we tried to use the microwave. It didn't work. We tried to use the one on the bottom floor but it was filthy. The rest of the hotel was in good condition. Just very poor customer service.
