Thanks for responding...been a little worried...DS is 12 so time to start...Heck if we can navigate getting through Magic Kingdom during a parade, I hope we can this...
LOVE SIGNS

Oh good, 12 is good. My guy is 8...first problem is that he's in the back seat still, LOL.
I think we've still only taken 417 away from the airport, and we took the other way (528?) back to the airport once. So I really only know 417, but yes, IMO it's easy. (I'm generally the navigator) Key is to stay to the right so you have easy access to the toll areas and don't freak out and miss them. Have money for the tolls (we have a ton of ones and quarters anyway) and it'll be fine.
fireman's idea of studying street view is a good one, too. There's nothing like having seen the route before!
Now I do find it a bit nerve-wracking to get OUT of the airport, but with many airports it's just a big circle, so as long as you don't go through any "do not enter" areas (as we did once, LOL, at MCO, we went into the area for taxis, but even they had a method to get out once you read their small signs) you can pretty much just circle around. Know where you're going, know basically where you are, read the signs.
Now I've made it sound scary while trying to let you know it'll be OK. It'll be OK. 12 is awesome, it'll give him great practice for 4 years from now when he's getting his permit, etc etc.
