I've never stayed at Lawson, but I did stay at Mary E twice.
From what I've heard about Lawson, it's not too bad a bike ride into town, but you're still going to be pretty reliant on the shuttles. No campfires and no shade.
Mary E would be a bit more extreme of a bike ride into town, but you'll find plenty of shade and you're allowed to have campfires in designated fire pits.
AS far as the shuttles go, as long as you plan ahead, you should be fine. I never missed an act I wanted to see when I was staying at Illium. My brothers did once and I've heard several people say the same thing. My advice is to pack up everything you'll need for the day (food, warm clothes for the late sets, money, sunscrean . . .) and make the trip in the morning. That way, you won't need to be shuttling back and forth. As long as you get in line early enough (sometime before noon), you should be fine. The TBF Shuttle drivers do an excellent job and pack as many people as possible onto those shuttles.
