Orlando and San Jose are about 2,407 miles apart by road. Split the difference and you arrive near Dallas, the city closest to the halfway point between them. That puts roughly 20 hr 9 min of driving on the Orlando side and 30 hr 23 min on the San Jose side — the fairest single meeting point among the cities near the middle.
Over this distance most people will fly rather than drive the whole way. Dallas still makes a fair, central place for Orlando and San Jose to converge, splitting the travel instead of asking one side to cross the country.
If Dallas doesn't have what you're after, Oklahoma City and Austin are also close to the midpoint and worth a look — each keeps the drive reasonably balanced between Orlando and San Jose.
