Real skinny with no BS:
Rent Bikes or Duckies (inflatable whitewater kayaks/or Tubes) at Confluence Kayaks (15th and Platte St) and check of why you pick Denver over St. Louis.
Across the Street from Confluence Kayaks is Brothers Bar. Great burgers and oldest Bar in Denver-sit outside.
See a Rockies game, sit in the Rock Pile Area tickets are cheap.
Call Clear Creek Rafting and go rafting one morning or afternoon-it's Colorado.
For stakes go to the Chophouse Restaurant at Wyncoop and 19th., or for your crowd you need to check out the DC Stake House lunch time Prime Rib special.
And ask about the Glendale Center for the Performing Arts, other accomindations can be found in the ads of the Westword.com
Super strength Margs goto the RIO.
Comedy Works is downtown, give them a call in advance and see if they will give you free tickets to one of their shows. They have a two drink min, damn.
Most of your deck bars and bigger bars are located a few blocks away from where you're staying. Your location is better 247 and being closer to the bar zone is better only at night.
Check out the Market Deli, Buckhorn Exchange, Red Rocks, get to Golden and take a free brewery tour at Coors and eat downtown at Woody's Pizza.
I love to dance, but who needs the music- It throws me off.
