If I could keep my big mouth shut, I'd tell them you are going somewhere else, and then just wind up at Disney. It will be cool to see what point in the drive they figure it out at. If you are on deluxe dining, I would definately just start the plan the next day. You should have plenty of credits, and I'm sure you can find something else to spend the extra $$ on. The only thing is, there might be a chance that you would have to move the next morning. It usually doesn't, but it would be a big pain.
