FYI: There's K1 Preferred Parking ($40-$45) and Snowshed Valet Parking ($45-$50). K1 is accessible to the K-1 Express Gondola, Superstar Quad or Snowdon Triple, as well as downhill skiable access to Snowdon Six Express. Mostly accessible via black diamonds, but also accessible by two blues (i.e. Bittersweet and Bunny Buster) and a green (Great Northern). An added bonus is that it's near the Waffle Cabin by the Snowdon Triple 🙂 Trail Map

Here's a link for more info. and to make reservations: Killington Premium Parking. Alternatively, reservations can also be booked via the ParkWhiz app.

The site says hours from 8 am - 5 pm, but my app reservation confirmation said that an earlier check-in from 7 am ("one hour before event") is possible.
