I second the Turkey Lake dr. Anytime we have had to go to that area this is how we go. Plus, why pass up on a chance to drive by Bay Hill Golf Course, or the tree that Tiger Woods hit befor his ex wife beat him with a golf club. lol
Another option is international drive.
I-4 is the closest, but with traffic could be the longest.
Funny, in over 20 years, we have never even entertained the thought of Universal. We used to do Seaworld every now and then, but that was only because the tickets were free for us (dad was an AB employee). Since the free tickets stopped, we no longer go there.
