Better explained:

example scenario: Half of all mountains close for 3/4 of the season, others remain open all season. In this case, selecting "all mountains" gives you 37.5% credit for a pass for next season. Keeping in mind that closures will likely be regional (say, at the state level), that's a bad deal if you live in a closed region and now you have to get on a plane to use your pass (selecting a single, local mountain would have you refunded either 75% or 0% depending on whether that mountain is one of the ones that closed). But it could be considered a good deal if you lived in the midwest and were planning on getting on a plane anyways (but now you fly to [open mountain] instead of [closed mountain]) (from reddit)
My goal is try to make a gamble and choose option 1 for the IKON resort that I think is most likely to be closed. NS, this is where I need you. Do you guys have any predictions for the IKON resort that you think will be closed for the biggest percentage of the season?
