Thanks for everyone's encouragement and replies. For an update, DS was in the hospital, and is home now. We should be able to head down on Saturday if things progress as they should. He's even weaker, though. Sue, thanks for the link to the stroller. I'm going to rent one today. It's perfect for him right how. He's 4' 6" but only 48 pounds so he's hard to find something for.
We've decided to sleep in, wing it, and dine in the places we normally wouldn't choose when using the dining plan--beaches and cream, fountain at dolphin, plaza, LTT lunch, etc. We're under strict orders to try and fatten him up and I think WDW is a good place to do that. The theme of our trip is "eating our way around the World" and I'm looking forward to it.
It will be hard not doing the commando thing, though. We need some sort of Commandos Anonymous group for reformed OCD disers
