Pros: The Vail airport location offers super quick in & out compared to flying into Denver. We were quickly greeted and were given a complimentary upgrade. It is so nice to deal with friendly staff - completely unlike our multiple trips to Denver and the understaffed off-site location that we continually encounter there.
Cons: misleading pricing during the up-sell pitch resulting in saying"yes" only to find an increased cost of 12 bucks per day! (not 4)
Only result was the line next to me processed three people/cars in the time it took me (1 person/car) to get my keys!
