I agree. Lots of people but it doesn't feel unsafe at all; of course, I never go into the lodge except for the Club (the "bubble") and the new one at top. But even up there the tables are spaced well, I don't see much of an issue.
BWC is totally worth it if you can fit it in your budget. I love being able to store my stuff there - and the boots are nice and toasty when you get in them, and while I didn't care of skipping lines before having kids since we always just skied midweek, now with kids it makes a huge difference. They do have a bit of a waiting lists - friends of ours had to wait about a year, but it probably is different now.
