I used them last September as they partner with the Candy Cane and I needed a last-minute scooter. The hotel arranged it, so I can't speak to that part, but here's why I can't recommend them:
I had a 24-hour reservation; from 3pm to 3pm. The Candy Cane does not allow them in their rooms, so they told me to bring it to the office and night and it would be charged for me. I did so. The next morning I went out to go to my ADR at Carnation Cafe and the scooter was gone. When I inquired at the office, I was told that D&R had picked it up in accordance with my reservation.
After 3 phone calls to D&R, a very surly woman picked up. I explained that it had accidentally been picked up and she said "no, you were done." I explained to her that I was not done and had paid for 24 hours. Her response was that someone would bring me another scooter in within 3 hours, and to wait at the hotel. I then asked for a refund as I would lose $20 on my ADR if I had to miss it. She laughed and hung up.
We ended up parking in the Toy Story lot, causing me to hobble in. We went home after our ADR and I successfully disputed the charge with my CC.
YMMV.
