Instead of Alligator Alley (I-75 north), can I suggest that you guys go across the state on Rt 41 (Tamiami Trail). It's a little slower but much more scenic - you'll have the chance to see plenty of gators in their native habitat. Also, there's a place called Clyde Butcher's gallery. Butcher is an accomplished photographer who has been photographing Florida and the Glades for many years. Much of his work has been compared to Ansel Adams'. I'd recommend a stopover (1/2 hour or so) at Clyde's gallery. And it's a GREAT place to see live gators in the streams surrounding the gallery and right across the street. You can pick up 75 North at the west end of 41 in Naples - easy to do and well marked.
