How do you pick the prospect days to go to? Some seem like they are real invites, but most are mass mailers. I don't want to make the investment to go to a school at this point if they really are just fishing for people to come. Of course my son wants to go to every one.
Sort by the schools that your son is most interested in. Then narrow by the ones you think he could possibly get into without Lacrosse. Then have either your club Coach/Director or HS Coach call those College Coaches and determine if there is real interest in your son. Not sure how much info the Coach can give with the new recruiting rules, but I'm sure your Coach will be able to determine genuine interest or not. If you don't pre qualify you'll just be making a donation, unless your kid is just a flat out superstar that everyone wants.
