Alright ...
New info courtesy of the club director (no, that's not me ;p )
The $350 listed for "Performance Training" (as listed
https://www.vajuniors.com/page/show/1453430-club-information) is
required for
ALL players this upcoming season. This amount is directly paid to The Fieldhouse.
The Fieldhouse is charging $25K to use/manage the facility for the season ...
before hourly court rates. In other words, the club still pays for court time on top of the $25K (out of the club fees, I presume). The club is evenly distributing this charge, resulting in the $350 per player fee. Again, this fee is being paid directly to The Fieldhouse. Sure, the club could have added the $350 to the fees paid to the club, but opted for this way instead.
That's all I know, so someone would have to reach out to the club for more info.
