Alright, I'll bite...
Definitely open:
Park Lane/Freeway obviously sick as fuck.
Stuff off of E Chair, all really good bump runs, the windows and doors are great for trees, and if you want some other trees that don't get skied quite as much head down Volunteer on Peak 9, then on the skiers left there will be an opening onto "Needles Eye" which is always pretty sick.
Horeshoe Bowl/contest bowl other stuff lookers left of the TBar are good especially if it is a powder day, the stuff lookers right of the TBar will hold snow longer
Might be open:
Peak 6 (hard to say, they are hoping before Christmas but it all depends on snow, but some of the terrain looks decent)
South side of Peak 10, the runs are like Mustang, Dark Rider, and they are generally pretty good/good trees back there/don't get skied off too quick.
Lake Chutes
To avoid lines:
Ski the Peak 8 super connect mid station. The trees between Rendezvous/Tiger are generally pretty sick and don't get many people skiing there, and then you just hop at the mid load of the superconnect and you can avoid the craziness of Breck a bit.
As others have said, the bus system in Summit County is decent. The Swan Mountain Flyer is running now so you can get from the base of the gondola at Breck to Abasin in 50 minutes so that isn't too bad, and you can get that same bus to Keystone and that only takes about half an hour.
Keystone gets a lot of hate because it is overall pretty flat, but there is good stuff at Key and no one really skis it so the snow stays good for ages.
