I love the Beechmont Facility. It is outdoors but with a roof to keep us cool in the summer and dry if it rains. It does have some limitations on scheduling as it is also used for recreational ball so I usually just use the facility during the summer days. However, I am working on expanding availability.
This is a great option for fielding lessons as I do have the field available.

Bathrooms are not typically available.
This is the least expensive facility option with many promotions going on through the year.
