Maybe you'd want to stop outside WDW altogether depending upon time.
In that case, keep watching billboards on the interstate.
I'm also assuming you'll be taking I-75 and then getting on the Turnpike in Wildwood, so once you hit the Turnpike, options will be very limited. Also, they've opened up a new northern entrance to WDW off of the Turnpike so you don't have to even drive through Orlando or even the main gate on Apopka-Vineland Highway (SR 535).
You exit at SR 429 (Daniel Webster Western Beltway) and take that south to Western Way which heads right into WDW by the CSR (turn left at Buena Vista Drive).
But if you do decide to hold out until you get to WDW I'd suggest either DTD or something on 535 (and maybe 535 might be the better choice because of all the options and possible lighter crowds eating).
