Not well in advance. I think the storm may have impacted the groups travel plans on Tuesday (speculation).I assume that the all-mountain rental was cancelled well in advance of the Weds storm. I wonder how much of a difference in revenue there is between a rental and a Powder Daize?
I can't say about the total net-net for the mountain, because F&B and rentals are a huge variable. But in terms of lift ticket sales, I believe the group gets 66% of the fee back for cancelling, mountain keeps 33%. At $88 a pop for tickets, with the "crowd" I saw, I think they made up that 66% (also speculation).
The other factor with a last minute cancel... staff is already lined up to work, solving a big issue with powderdaize, getting staff on board for a "non-scheduled" workday.
