V.P.
You might look into local libraries and rec centers. I know the ones in Flower Mound both offer rooms. Also in Flower Mound, Pinewood Hills Retirement Community has a nice room that I've been to attending various PTA/Communities in Schools events. It's free for the PTA - not sure what they might charge individuals. They have a small kitchen in a nook at the side of the room, which is nice.
