Definately bring a chair, I am disabled myself and last year was a nightmare. Even though people could see I was using a walking stick and having difficulty standing people would not give up a seat for me. I think Showmasters do a fantastic job on the whole, but they do let themselves down when it comes to people with disabilities, I am more than happy to get to the venue early and stand in line to get tickets for the guests I want to see, unfortunately my body just won't let me physically do it so I miss out. Hopefully someone from SM will read this and give the matter some thought? I spoke to them at CM15 but they said it was stand in line or miss out and there was nothing they could do.
