I promised myself I would post to this thread when I returned since I found it and
http://allearsnet.com/tp/rid_trip.htm really put my mind at rest before my trip.
Overall I didn't have any major issues with my size at Disney (6ft, 330lbs). Here are my thoughts from what I can remember:
Circque Du Soleil - I was very worried about this - I heard that the seats are very small and very uncomfortable, but I had no problems - I had lots of leg room, and lots of bum space.
Magic Kingdom:
PotC - would have been okay, but the CM put myself, my hubby (also "Pooh" sized), and another couple who were a little on the heavier side in one row, so it was very tight - would have been fine with just 3 people.
Thunder Mountain - remember this one being hard to get in and out of when I was a kid, but hubby & I fit just fine, and had no problems getting in or out.
Haunted Mansion - no problems. I can see the turnstiles would be a problem for someone shorter, but luckily for me my legs are so long that the majority of my bulk is up higher...
Buzz Lightyear - no problems - lots of room for my legs
Epcot:
Mission Space - no problems at all - I could see if you were shorter the restraint could be a problem, but my long legs & arms saved me.
Test Track - unpleasant! We were in the back seat. Seating is for 3, but luckily they only put the two of us in it. I didn't have enough leg room, so my knees were jammed, and the seat itself was very tight - had to have hubby buckle up my seat belt & unbuckle it for me at the end. There was loads of room in the seat belt - actually too much - I couldn't cynch it up once it was buckled, so I had a good extra foot of belt around my waist.
Animal Kingdom
Kali River Rapids - only place I was embarrased the whole trip - found the one CM to be very rude. First the people in our raft didn't want to move over to make room (first group in was a group of 3, and the seats are in groupings of two), but the CM kept insisting my husband and I go on - so we end up splitting up two women who were together, and I sat with one of them (she was a little on the chubby side, though not as over weight as I was). The seat belt did not fit around us. I called out to the CM, and he just ignored me - I had to ask 3 times, and he still ignored me - by this point I was PISSED, so I just got up and got out of the raft - at this point the CM finally realized something was going on and directed us to another raft. He told the CM at that raft to allow my husband and I each to have our own seat... The ride was fun, but if I ever go on it again I will know to speak up for myself from the start...
MGM
Drew Carey Sound Stage - very very small seats - smallest I found the whole trip.
