I have seen people ride in the rain - however, like any activity with an element of risk, it depends on the intensity of the rain. If their is lightning in the sky, they would obviously close the track until it is deemed safe to resume activity.

We've always gone first thing in the morning right before it opens when not too many have arrived although even when busy the lines move quickly. The ski lift up to the track takes around five minutes, then before your first run down the amazing staff will teach you the controls of the car but for the actual ride down, i suppose that depends on how fast you let your car go but id say around 6 to 8 minutes, maybe. It's definitely a lot of fun, a great time spent outside and with friends/family doing something a little different.

Pricing is at their website, google skyline luge Calgary. Calaway is just west of the city limits and COP is fairly close to the western city limits so... it's not far, maybe a 15-20 minute drive. Stampede grounds are downtown so perhaps a 20-25 minute drive. I'd give your group a solid hour to do three runs each. My husband and I did 5 runs each today and it took us about 90 minutes.
