Thank you to the folks who have posted their experiences in this thread! I have read through the entire thread and the information everyone shares is so helpful and puts my mind at ease.
Hopefully I can pay it back somewhat by sharing my experiences, too. I am a frequent traveler to WDW, but the past several years I've been going with someone who is not a lover of rides (hence my many annoying questions about specific rides I haven't ridden in about 50lbs or so). There will be more rides for my next trip, so I am trying to be prepared
Here's my ride experiences from my last two trips - September 2012 & March 2013. Both trips I was a size 30 in Old Navy jeans, 4x Old Navy top, 5' 2" and carrying most of my weight in my belly and behind.
Magic Kingdom
Wedway People Mover
Little Mermaid
Peter Pan
Mickey's Philharmagic
Hall of Presidents
Tiki Room
Pirates of the Carribean
Jungle Cruise
The Many Adventures of Winnie the Pooh - The opening to the "honey pot" is sort of narrow; I stepped up on the edge of the cart to try and get my belly above the clearing and slid in sideways.
Carousel of Progress - I did not go through the "old school" turnstile, asked CM to unhook chain and let me walk through other gate.
Buzz Lightyear Space Ranger Spin - Skipped this in March due to September ride. I noticed when the CM "closed" the cart after we sat down (it's sort of similar to the doombuggies in the Haunted Mansion) the bar right at the Astro Blasters guns hit right in the biggest part of my belly and stopped. Uh oh. The very nice CM didn't make a big deal, just let us go even though there was probably a 2 inch or so gap preventing the cart to close. He just kind of pretended it didn't happen.
Haunted Mansion - Skipped this in March due to September ride. I obviously did not take the Buzz Lightyear incident as the warning it was and rode HM. Well, had the same issue with the cart. After we sat in the doom buggy, the CM went to close the cart and it wouldn't close all the way since the bar hit right at the biggest part of my belly. Unlike the Buzz CM, this CM was not so discreet. She pushed on the cart mightily and made grunting noises as she did so, I was mortified. So she finally got it shut enough to her satisfaction and away I went, totally ashamed. Remembering this experience has motivated me as I lose weight for my upcoming trip, though.
