I think I asked this on another thread-I hope I'm not repeating myself on this one-but how hard is the drive to the parks. I'll have a gps, but I'm from a small, small town and the driving makes me nervous. Still plan to do it, just worried about the logistics!
We live in a small town too so I know what you mean. The drive from WH to the parks is quick and easy tho. We have stayed at WH twice now - once in October and once in late June - and we did not find the traffic to be bad at all. You'll hang a left coming out of the WH gate and that road takes you right back out to 192. You can go right and follow the signs that will take you to the main gate into Disney property or you can go left and follow the Sherbeth Road route (which seems to be the quickest way to Animal Kingdom). DH always does the driving and we've only done the Sherbeth Road route once so I don't recall the exact details. But it's easy to find more specific directions here on the boards - they've been posted several times so you should be able to pull them up in search.
The only thing I can think of that might be tricky is finding your way back from the parks after dark. I seem to recall the signage for getting back off property wasn't that clear. But I'm afraid I can't be much help on that one - DH likes to "experiment" with different routes so I'm not always sure just where I am.
