there is no significant 'rush hour' between MCO and Cocoa Beach
'heavy traffic' in the area means waiting 'til the second cycle of a traffic light, and this is unusual!!!!
I live 15 miles south of Cocoa Beach and can go from airport terminal parking to my house in 50 minutes on an average day doing nothing crazy ... just staying with traffic.
NOW of there is an accident on 528, forgetaboutit as there is no good alternate route that won't cost an extra 30 minutes or more IF you know ahead of time and can get to it ...
************
if you plan to pay cash for the two tolls I highly recommend you have quarters so you can use exact change lanes ... the one place traffic can back up w/out an accident is the attended lanes at the two toll plazas .... {two tolls: $1 and $1.25}
