Don't worry about any thing. As others have said, Disney does a great job for us Pooh sized folks. I am 6'4" and weigh about 395 pounds. I have ridden everything that I have wanted to including Expedition Everest, Spash Mountain, Rockin' Rollercoaster, Space Mountain and many others. I have not tried the Teacups because I don't like spinning rides like that and don't think I can fit. I don't like to ride Space Mountain because it cramps my long legs. I have never found a ride at Disney I couldn't fit in. One of the biggest tips I can give any Pooh sized person is to pull out the seat belt before sitting down, this makes it easier to buckle up after seating. Also read the link to Deb's site that is listed above, it has a lot of good information and is very reassuring. Go, ride and have a great time without worry of not fitting in any of the ride cars!
