We've visited COP various times over the past few years. We tried luge, sports hall of fame and today we took to the snow tube park.
I called ahead to inquire and we were directed to overflow parking. Within 7 minutes, a free shuttle picked us up to take us to the main lodge where there was a large line up for tickets. It moved quickly and we had our cards in hand within 15 min. We walked to the tube park to pick up our tubes and used our cards to get through a gate that leads to a walking conveyor sort of like those moving walkways at the airport. The conveyor took us up the hill where 5-6 tube lanes were open each with an attendant. The hardest part is navigating past all the people who bunch up at the first 3 lanes rather than walk a few extra feet to lanes 8 or 9.
We asked if they were allowing doubles or triples where we could go down as a family of 3 holding on to each other's tubes, but due to extremely icy conditions and the speed travelled, we were only allowed Single rides. There are black mats to slow you down and bumpers to catch you from crashing at the bottom. We even tried a spin where the attendant will push you with a twist so you'll go the entire way down in a spiral. It was hard to stand up after that, so I only did the spin once!
We were there about 2.5-3 hours and were exhausted after 7 runs. Definitely going again!
