Everything went smoothly on drop off but return was disasterous. I called the number stamped on my receipt and it went to voice mail that wouldn't accept the message as "mail box full" then hung up on me. This happened twice while we waited a total of 45 minutes for shuttle that was surposed to circle every 15 minutes. When I finally called the hotel desk they said I was on "wrong level, need to go upstairs to different door to wait". I was never told of change in shuttle route when we dropped off car. Waited in freezing weather for an hour. Unacceptable performance. Could have been avoided with clear communications from clerk on day of drop off. Will not use this service again.
