I just returned from 9 days in Orlando. Went to the Disney parks 6 days. We had a wonderful time and the kids loved the parks. One thing I was very disappointed in was the rudeness of people. People would think nothing of running over a 5 year old. They did not think lines were for them they would push you and walk right around you to get to where they wanted to be. Anywhere from restrooms, nightly show endings, tram lines, or just walking the parks in general. This was our first trip to Disney, and due to the rude tourists I would never want to stay on Disney property.
I was very happy to go back to our off site townhouse each night and get away from the people and have quietness!
My advice is to bring lots of patience with you to Orlando, and prepare yourself for lots of nasty people.
