I guess it rather depends where your normal seat is - wouldn't want to try high up main stand, with lots of levels from entry point to negotiate/too far into middle of row - but have seen crutch, or 2 stick users near ends of rows as regular users, where they just have to negotiate main steps. I'm sure they let you through gate or door by turnstiles rather than turnstile itself if that was awkward, but I'd be inclined to contact the club and seek their advice in the light of where you do sit I think.
