Glad to share with you a little info.
I have stayed at all the properties in CS, and really like to stay at the RI, right across I-25 from The Air Force Academy. There is nothing like buying your own steak or bison steak and having a cook-out on their grill and enjoying the beauty of the area. Likewise, the fresh air will have you sleeping and ready for a great next day.
For that next day, or one of them, take the bike ride. or even walk, down Pikes Peak. It's 13 miles of pleasure! After that or during your trip, have a meal at the Broadmoor and enjoy the neat place without having to stay there. There is really something nice about eating there and then going back to the peace of your RI room!
One more thing if you can, if you go to or through Denver, I have one place you should eat one dinner! The Buckhorn Exchange, there is NO place on the planet like this place. It is a classic for game, rattlesnake, or just history.
Lastly, on your way West from Denver, go to VAiL, and get a good rate at one of the hidden gems in North America, The Marriott in Vail. Got an upgrade on a rate of $125 per night and this place is just like Switzerland. Good Fun!
My family traveled to Denver last weekend for a wedding. We stayed at the RI on Champa St. in downtown. Great spot, centrally located with a friendly helpful staff. They have an honor library, free Internet and a cozy lobby. They offer a fabulous breakfast buffet every morning and dinner M thru Th with beer, wine and soft drinks included. This is great if you just want to hang out after a long day. We walked everywhere. Have a gelato at Gelazzi on Larimer St. Panzano's is on the corner of 17 & Champa, a terrific Italian restaurant with a good wine list. Go to a Rockies game if they are in town, the ballpark is so cool. We toured the Coors Brewery-more free beer! Vail is a 2 hour drive and definitely worth the trip-have lunch at Sweet Basil.
Enjoy your trip!
Jerry Morgan is right about the RI at Interquest (that's the one that he's talking about). It's pet friendly and about 3 miles north of Colorado Springs. There are lots of diverse things to do in the Springs (everything from Pike's Peak to the Olympic Training Center to the Pro Rodeo Hall of Fame) plus if you have kids, I'd take them to Focus on the Family (about 2 miles south of the RI). CS is also a great place for outdoors activities (running, biking, hiking) and there's great rafting on the Arkansas River about 1 1/2 hours south (Canon City).
For the Denver Metro area, the RI at Park Meadows (there's also a Courtyard and Fairfield there) is convenient to the metro area without being downtown. There's a great zoo and Museum of Nature and Science in Denver, plus a lot of parks and the Botanical Gardens.
If you go west, the mountains are transitioning from skiing to mountain biking, and you can probably do both in the same day.
If you're a train buff, there are several antique trains that run in Colorado. Probably the best is the Durango to Silverton, but that's more than a toll call down in the SW corner of the state (we went last year and loved it).
