to the OP, this was all discussed within the past month; you'll find a lot of great info doing a search. Early morning midweek there aren't queues unless it's a powder day. Some lifts open earlier than posted times. Blackcomb is less busy than Whistler in general, but if you know how to ski Whistler you'll not wait in line much even on weekends. Get the official WB app for your iphone/android phone if you want to see lift wait times in realtime--it's my favourite app.

When ducking the "patrol boundary" rope be sure to know where your going or at least tag along with someone who does.
Agreed with watching carefully for patrol boundary signs at WB. I still don't know why some of the signs are permanently up (since you can see the rest of the run on the other side) but you can really get yourself in trouble if you don't know where you're going.
Peak to creek is often the worst skiing on the mountain. I find the grooming is inconsistent at different points - and since it's one run, you can't just peel off somewhere else. Also, you're skiing through multiple climate zones on that run, often getting powder, ice, bumps, and slush all in one run. It's a scenic run, and good for intermediates who want to feel like they've finished a marathon, but not much of a treat for someone who has a more specific idea of what they'd like to ski.
