Best way, 75 south to Florida Turnpike, way before you get to I-4, exit @429 south (new turnpike), a few miles (?20) down the road exit at Western Way? exit 11? (Disney back door- watch for signs). Tolls about $3.00 total, but much faster and NO TRAFFIC. Did it beginning of Aug. and it was fast. No I-4 or 192 traffic. (If I got the last exit wrong, someone correct me)
I guess it depends what part of GA you are coming from. We are about 70 miles from I-16 so we always take that to I-95 then I-4. It has taken anywhere from 5.5 hours to 7.5 hours.
We we be making trip 12 onFri. Dec. 22nd stopping in Jacksonville and heading the rest of the way Sat. Dec. 23rd.
