Diana:
As the Stace Shuttle suggests, TKI is likely your best bet, big airport with pleasant service (do not go looking for cheap gas, $4.79 Sunday), plus it benefits from the good karma of having been the field at which I soloed.
You could also contact Bo Boggs ("The Old Man" here), who bases at Aero Country (T31), which is a very nice little field a little closer to Frisco, and (perhaps) more your style. Aero Country has no "public" parking, but I suspect that you could arrange something easily enough with a little advance planning. No fuel there, but there are several fields in the vicinity and on your route with good fuel prices.
Finally, depending upon where in Frisco you may be, Addison (KADS), my home plate, could even work; Frisco's a quick "pop up the pike," so to sepak, on the Dallas North Tollway.
Sadly, there was an airport at Frisco, KDDJ, brand-new and ready for development, but the forward-thinking Frisco City Council bought it for the specific purpose of... closing it. You can still see a nice runway... in dirt where the concrete was.

Keep us posted on when you're headed this way; I know I (and others) will want to see, and feed, you.
