There are not a lot of beginner runs at Bald Mt. The greens you see on the map would be considered blue runs on most west coast resorts. And most of the black runs are not super difficult but all mogul runs (some very long). It is a GREAT resort.
We did not have any lines and that was over MLK 3-day weekend.
Start your morning on the left side of the mountain (Seattle Ridge) and then move you way to the right as the sun moves.
