I can't wait to see you, Joyce and Lisa in a girl fight!
Cheese Pretzels...not sure on that one. The one I got was in Germany in the WS and it was SOOOO good. Crunchy on the outside, soft in the center, salty and sweet. It was yummy. I am craving one. I am on a diet...can you tell?
Stroller...I would seriously consider either taking your stroller (do you ever use one?) or renting a special needs stroller for your trip.
The strollers at the MK are so...hard. They don't recline. I would not want to sit in them over long periods of time.
William is a perfectly healthy 10 year old and we had to rent him a double because he just got so tired. But it was not very comfortable for him. He eventually gave up and they took him back to the room before Wishes one night.
The walking is just so much in Disney. And TONS in Sea World. Not sure about Universal, but I would assume more of the same.
They have special needs strollers that can be rented and delivered and picked up right at GKTW.
Here is the main site that does this and is the one recommended by Mom's Panel, DISboards and AllEars.net.

You can also get a "stroller as a wheelchair" tag - which I would do so that you don't have to park the stroller as much at Disney and even the lines can be long.
And your other children could even ride in it. They will get tired, too.
