From the I-4 on ramp on Apopka Vineland rd by Downtown Disney (exit 68) to I-75 north (exit 9) is 59 miles,then you drive north on I-75 for 4 miles to Fowler ave west (exit 265).Go west on Fowler for another 4 miles or so to turn left on Mckinley.Total trip is about 68 miles,taking into account ground streets in Disney before getting on I-4 and ground streets after getting off I-75 so more than likely you're in the 1.25-1.5 hours.I went from the Disney area to I-75 in about 50 minutes or so one Sunday night with absolutely zero traffic and even then it would probably take me 1 hour 5 minutes to reach the park,add in a bit of traffic and you're likely to be in the 70-75 minute range unless there's an accident or slowdown.
