AITA for expecting accommodations for disability?

I wish I could show a picture, but it's this- a community centre with a hockey rink surrounded by a walking track, in between these two things is seating, a lot of it. The rink is slightly lower down than the walking track. Anyway, I have MS and have been using the track to walk in the mornings, and I have to hold onto the rail between the seating and the track. Spectators stand in the track, but also hang onto the rail as they watch hockey and will NEVER move for me despite that I clearly need to hang onto it, some days very visibly struggling. Where the AITA comes in is that I'm told at home that I am overreacting and that it's a rink first, track second, so being that no one moves for me and I have a partner at home thinking I'm being unreasonable, am I?
