I used Randy's Mobility for my 8 day stay. It cost me $180 for the week. They delivered it to me right where I was dropped off at the hotel. At the end of my stay, I just brought it up to the front, where they keep people's luggage, and they were going to pick it up there.
I had a positive experience, though if I were to rent one in the future, I would probably bring a small pillow, or lumbar cushion as my butt really hurt at the end of each day.
