Just as a follow up to this thread, Keystone was really not crowded at all on Sunday (given it being a weekend+Spring Break). Granted I was only in the park and front side in the morning. On the backside the longest I waited was a minute or two, nothing significant. I was on the front side a bit in the early afternoon and I waited for Montezuma lift, but it was 10 minutes or less. North peak lifts had almost no waits, and it was pretty empty. Went back for night riding and didn't wait for the gondola or lift at all, runs were pretty dead on the front side.
Breck on Monday was WAY more crowded than Keystone on Sunday. As you put it, the lower runs were pretty much a shit show, lol. Tried riding in the park but the lifts that service it were taking way too long and stopped every 10 seconds from people falling or sitting on the chair after the exit ramp and riding it too far lol. No joke, I saw that happen twice on chairs in front of me on the 5-chair. So I just went to upper terrain on the 6-chair and Imperial Express when it started getting more crowded in the late morning. Base lifts had a longest wait time of about 20 minutes for me, and I came down to the base about 12:30 and got back on the Colorado Chair in about 10 minutes. No waits on Imperial all day, longest wait on 6-chair was when it stopped for about 5 minutes straight, so the line had backed up, but when it started moving again the line died out.
Overall a pretty good trip, much better crowd wise than I was expecting, snow was patchy in spots on some of the upper spots, but there were still some pretty nice spots given the lack of snowfall. I think the lack of crowds this year might be attributed to the "bad" snowfall, although being from the midwest the amount of snow you guys have out here is better than the snow we haven't had for the past few months.
