In terms of enjoying yourself at a tournament (pool play competition may not be very high) it is hard to beat the Slumpbuster tournaments run in Omaha during the College World Series.
We just went this summer. They do it during the week of championship series, Start Tuesday, end Thursday. Part of it as I understand is players get a ticket to each game of CWS championship series. Scheduling wise they make sure games will be done in plenty of time to go. Competition this year was ok.
One team there (MVP something), were part of a recruiting serivce and had college coaches as the coaches, Otherwise, this was not a tournament to be noticed by colleges.
That being said, we had a wonderful time. We went as an 18u team when all but 2 of our players were set for their college choice so being recruited was not high on the priority list this year. BTW, one of those 2 was contacted by a college coach that coached that MVP team, so you never know
