Thanks! What I've read so far has me real fearful of the crowds.
Haven't skied Heavenly in a few years, but the biggest line was at the gondola so make sure you get in line early. I thought the neveda side was less crowded. Hopefully some current locals can give you more updated information.
There will be zero crowds in Mott/Killebrew I bet. If you want killebrew or gates 1/2 on mott you'll have to add the dipper chair to your laps. You can get most of the good stuff in mott by just traversing. Also you won't find much for crowds in the Northbowl area. Gunbarrel chair should be ok if they reopen the top part of the face. Everything else will be a shitstorm.
Also if the gondi is packed then hop the bus over to Stagecoach and start your day there. There's more I could say but I'm not spilling it online...poke around, the best stuff at Heavenly is far from where the people are at, lots of people lap sky and dipper chair and assume that's what its all about for the advanced skier...there's much more
