In the thread about splitting up many people mentioned that one of the rare times they split up was when they didn't want to ride something or their significant other didn't want to. DW didn't want to ride the Tower of Terror for the longest time, but when my mom came with us one trip and rode it with me she finally gave in and loves it now.
So -- What rides have you never ridden and for what reasons? And what rides have you ridden that you don't plan on riding again?
