My kids just want to ride on their sleds, what's the fee for this? Do we have to buy lift tickets?

Not sure, but you will have to buy ticket

Great question. We don't allow personal sleds in the tubing park or snow play area but your $30 tubing ticket includes one of our custom tubes. Hope this helps. Please see here for more info http://www.mthigh.com/site/mountain/events-and-activities/yetisnowpark.html Looking forward to seeing you.
