As for what to do in C. Springs, first of all, get out of C. Springs. Honestly, there's not much to do there. Somebody mentioned the water park in Denver, and that is a must. There's a reason they call it Water World. I'll have to go one more time before my life begins. haha
Anyway, Denver is just an hour up the road, and that's where you'll find all the interesting things. There are a bunch of small venues scattered around the Colfax area where big bands tend to come play, and the CO music scene is solid, so even if you don't know the band check them out.
You'll find pretty much all the attractions of a moderately large city in Denver, so if you want to have some last minute fun, just explore the Mile High City.
