My dad has a progressive neurological disorder and this is our third trip to DW since we noticed something going on. I have some connections at Disney and wrote an email with suggestions/observations after our trip and posted it on my travel blog if you are interested. It might be helpful to a few people. apparently I'm not allowed to post links yet. But you can Google WhereTheMapGoes. Plus, you should check out the Rolling with the Magic blog. REALLY helpful.
