I feel pretty confident they aren't going to allow other mountain pass holders on for First tracks. We have to go to Guest Services to show our pass to get a ticket, so I'm sure it'll be a day comp that won't register as a SP and open the gates early, assuming they have it set that way to figure out who to let on easily at the lifts.
Here is the parking map. Lot 2 and lot 3 are premium lots. Since they said free General parking, I expect these will still be pay lots. Lots 4,5,7,8 lots are normal paid or season pass lots that should be free tomorrow.
Here is a satellite image. Red squiggles are premium. Yellows are free, green is lot 8, this is where i intend to park. It's down the hill back towards the hotel, right next to the beginner Sunbowl slope. It's actually the closest parking to the snow, but not the most convenient to the good lifts. Either have to ski over to the Sunbowl quad and catch a lift up to the new bubble, or down past it to the indoor Waterpark lift and ride thst to the top. That's probably my plan, with a Nile Mile run first, then a trip back up and head lookers right to get down to the other lift and see what's good over there.
My plan is to arrive about 745, park down by Sunbowl, walk up in street shoes to GS for my ticket, then back down and boot up. I only have until about 1030 because Boy 1 has a soccer game at noon.
