You are actually just a short distance from exit 242 on the Florida Turnpike.

Take this North to exit 249 then take Osceola Parkway east directly to Disney enterance.

If you carry on to exit 254 that's the Florida Mall or take 528 East to SeaWorld

If you stay on till exit 259 that's Universal and the Mall at Millenia

Only down side is that these are toll roads and will cost around $3 per day. However journey times are quick so you will not be wasting time stuck in traffic.
