There is a strong level of competition this year. There were definitely schools at the last event, but my son was playing 14u I think so that park didn't have the draw that the other parks had. Prospect Select does a pretty good job of blasting stuff out on social media.
If I were looking into hotels I would look for something in West Palm Beach. Palm Beach Gardens has nicer hotels and restaurants, but West Palm is central to the parks being used for the event. The last time they held this tournament they used a park called Santaluces Sports Complex and Ballpark of the Palm Beaches. I see this year they are also using Roger Dean and Lawnwood. Lawnwood is in Ft. Pierce and will be the only park that is out of the way. Probably 45-60 minutes from West Palm.
