Sounds like you just want to find a friendly with a team that has a facility.
East Central High school out in St Leon used to do a weekend or two with double headers out of their field house. They also had 3 game fall friendly’s outside but it’s been years since we played there.
To get an idea of indoor cost SWOBAT wants $750 for five indoor January games.

I still think the SC events are your best bang for your buck if you can get in.(Teams need to plan accordingly for any winter events since they are so limited).
SC usually will run several weekends at various age groups. The ladies get to face live pitching and get to play basically 3 friendly’s for a decent price.
When Colerain stopped doing SWOBAT in 2012 we did two tournaments at SC one HS the other a 16/18U mix of teams in 2012 and 2013.
Lebanon and a couple other HS did the same thing for the money its worth a little drive.
