Went to Wisconsin's camp back in 2006 as an freshman in high school. Was on a Frisbee team that Solinsky coached. Fast forward 9 years i'm now about to graduate college, damn i'm old.
My take the Wisconsin camp is awesome. You have athletes from the team as your counselors and there is a ton of fun stuff to do in Madison. The camp had dances, ultimate Frisbee, good food, and good looking girls. You get to go bowling, swimming, cruising state street, etc. There is a good deal of running, twice a day, and presentations on running but plenty of time for fun. I hooked up for the first time with a girl at this camp. The dorm life was wild and pranks were always happening. We stayed up late and woke up early but had a blast.
I'm sure the Solinsky camp will be amazing. I don't know so I can't compare the two but I would not trade camp experience as a high schooler. It was so much fun so go to either and you will have a blast.
