Wanted transmission service and air filter changed We called ahead before arriving and were informed that it is first come first served. Upon arrival we were informed that they would definitely get to us today as there were only a few vehicles in front of us having PM work done. Four hours later, after unhooking the car and trailer, sitting in the mid-day sun, in a wide open parking lot, with all the slides in to be ready in case they come get us, we were informed it would only be another 2 hours. 3.5 more hours pass... Finally after checking in one final time we are told they will not be able to get to us today. And may not be able to get to us tomorrow! We are told that we can spend the night in the parking lot, but if we want power we will have to move over to the parts department. We decided we were fine without power and to stay put. I went back the rig and put out the slides and leveled the coach a bit for comfort. The parking lot was all concrete so there would be no problem with sinking into the asphalt. We settled in, had some dinner, walked the dogs and watched a little TV. Around 10pm we decided to hit the hay. At 10:50pm I was awakened by a knock on the door. It was the night manager telling us that we had to move to outside the parking lot! They just watched us setup finally and get comfortable hours ago and waited until 10 minutes before they were closing to tell us that we now have to leave! Horrible experience. Would never go back.
