At Jackson I drive half way to Teton Village and park for free at the Stilson Lot and get the free shuttle to Teton Village. If you get their early enough there are free granola bars and coffee and washrooms in the heated change room. No cubbies.
Sun Peaks has tables and chairs in the Village Day Lodge (VDL) Great Hall. Downstairs their are more tables and chairs, shelves and hooks, small coin lockers, vending machines, and washrooms for the public. There is also a private locker room with combination lock entry.
This private locker room, well the actual lockers really, are the gold standard for ski lockers. They are very wide and can accommodate 4 pairs of skis and there are 2 stacked shelves that hold one pair of boots each with tubes pumping room temperature air into the boots. There is room above the boot shelves to build more shelves as some have done or just stack several plastic bins.
I was on a waiting list for 7 years before I got my locker and then it was only because some people dropped out when they changed from season to year round rental and doubled the price. I should probably leave my locker to my beneficiary in my will.
Oh yeah, when you head out of the VDL from the locker room to the skiing, one chair is 100' away, the other 200'. And should there be an electric power outage, no problem as the two lifts outside the VDL have diesel backup engines that run at 80% capacity of electric and the VDL also has its own backup diesel generator.
