When does F Lot fill up?

I have a condo booked for Friday-Sunday on peak 9 and will have to move my car after checkout on Sunday, but would like to ski for the day so trying to figure out the most convenient parking option.

It looks like F Lot is a short walk from the condo and I’m looking to stay walking distance to Quicksilver so thinking about parking there (cheaper than Beaver Run). What time does F Lot start to fill up? Trying to determine what time Sunday morning I should move my car there by. Thanks!
