(19 year thread bump!)
Staying here at the start of a group tour and called the hotel to confirm airport shuffle info from the website:

Airport shuttle
Denver, CO [Denver International Airport], US: Available, Fee applies, 24/7, $5 round trip
The "press 1 for shuttle information" automated recording announces the schedule and pickup location but doesn't talk about the charge. However the front desk confirmed that the $5 fee started this week, which seems strange and unfriendly for an airport hotel -- were people abusing the free shuttle to get to oen of the other nearby businesses? The Tru and Courtyard still seem to have free shuttles.
We're locked in, so don't have a choice, but FYI...
