Wanted to post a link to a reply I just made in another thread where I show photos of myself and my husband, both solidly pooh-sized, on some rides (7DMT, Space Mountain, Test Track, EE). I'm 5'8", 300-ish lbs. He's the same height, weighed around 350-360 in these photos. Sometimes seeing the photos is helpful for folks who may otherwise be having some anxiety or doubts about whether they can participate!

I relied heavily on the comments here for the encouragement I needed to have a good time in WDW for my last few trips! Wanted to pay it forward
