1. Please stop installing barn doors for the bathroom. They are loud to open and close (at night when someone is sleeping) and provide zero soundproofing (people are awake hearing others go to the bathroom, brush their teeth and shower-ridiculous!). 2. We needed to use the pull out sofa as I was traveling with my two children. I called down for a blanket and pillow, which were never delivered. 3. We were in town for a funeral and stayed two nights. We did not receive maid service on Friday even though we had left the room by 10am. It was disappointing to come back to the room after a long day not to find fresh towels or the room spiffed up. 4. I honestly think the hotel thought we were there with a travel team, but we were not. We've stayed at this location a few times and there are always kids running up and down the hall at 1am. I'm not sure what can be done about that, but the barn door, lack of maid service, lack of blanket and kids running (oddly less of a concern as I have children) was not what I had in mind. The DoubleTree should be better. This felt like a 2 star hotel.

Only for a brief stay

Air conditioner was constantly running or cycling on and off to maintain 71°. Smoke detector was mounted over one of the beds and it had two green lights which flashed intermittently and was a distraction with all the lights out during bedtime. The bathroom did not have an exhaust fan.
