Highly recommend lining up lodging now.
Would recommend Green Lake...just 20 minutes SW...gets you away from all the traffic and crowds. The Heidel House Resort is nice. Also, would look at Fond Du Lac. heading northbound on Hwy 41 is difficult with all the traffic and construction going on.

also, highly recommend camping! If you don't want to sleep in a tent...you can rent a camper with Air Conditioning.

looking forward to having you join us in 2013!!

blue skies and tailwinds!
