i still think the whole "not enough rooms" thing is overblown
the green bay metro has a population these days of 320,000 people. appleton metro has another 243,000 people. so the whole idea of green bay just being a little ho-dump area is kind of a myth
there are plenty of hotels and motels in the area. plus i think most people that will be attending will be locals (all of wisconsin and the UP) there for just the day
