I never had a problem with the wall.
Last time i did SRO was for Les Miserable's closing night and the wall was up to my chest.
I know I am short but never had a problem with the SRO walls.
And I think it is stupid that disney actually has height restrictions. It's one thing if they warn you and give you a heads up and let you make your choice about it regardless. But, its another thing all together to determine if they sell it to you or not based on your height. They're getting your money so they shouldn't be so picky.
