We want to go to US/IOA for about 6 nights/7days. I am concerned that there won't be enough for us to do to warrant staying that long. Furthermore, unlike Disney, I don't think the US dining plan or meal ticket is all that great, so I am afraid we're going to spend a fortune on food. We really want to go because we love theme parks and thrill rides, but I have some worries that hopefully you all can help me with. We won't have a car nor do we want to rent one, so driving around is not an option.
