The JW is about 15 minutes in the opposite direction of 4 rivers from MCO. You'd take 528 the same direction for both, but then take either 441 north or I4 east for 4 rivers, or 441 south or I4 W for the JW.
One option might be to take the long drive past the hotel (or stop at the hotel on your way over) to disney springs and grab lunch there. Lot of restaurants.
You'll also be passing OBT, which has dozens of restaurants for every foot of road.
Can't really offer any recommendations along that area sadly though. No personal experience for me as I've never flown into MCO.
When are you heading to orlando? Delta is gonna start earning points in february I believe. I'm staying at the Castle this weekend. I've stayed there once before, it's decent. I normally stay at the Springhill Suites Orlando Kissemmee. Nice property, clean rooms, they have a little bar at the attached hotel with decent cheap food.
Raglan Road (Irish pub-fare) in the Disney Marketplace Village is a cool place. Or a couple nice restaurants in Celebration: Celebration Town Tavern and Columbia. They have outdoor seating. Also, Cafe Tu Tu Tango, mentioned by AZDesertRat, is fun.
