Top 96 has been around for a while. They were independent previously, then formed a partnership with Under Armour. Seems like there is a connection to HF. I found the camps very successful and well run. They were good with their flexibility as well. Son had a collision in CF the night (or two) before he was to attend a showcase and they allowed us to switch showcase dates/locations without penalty. Son was looking at HA schools and these showcases gave us an opportunity to look at a number of schools he was vetting and vice versa.
Got good bang for buck. Son had been in contact with several schools in attendance so he was on their "clipboard" when he arrived. I believe he went to one Top 96 summer before his junior year and another early summer before his senior year. As you mentioned, several locations available results in less travel. Cost much less (1/2? of HF). The cost also used to vary per camp depending upon the # of schools there and what schools are in attendance. Good luck.
