From our experiences, I would say I've been disappointed with Premier League provisions for disabled fans. I think, in our first season up we had more wheelchair spaces at Dean Court than Old Trafford. Although they do have the best wheelchair accessible meeting room and it's open and advertised to visiting w/c users. Unlike the Emirates, they have one but like to keep it to themselves. Very few have one, although we do.
I've just realised, I could go on all night about our road trips but I'll try and stick to accessible parking. Not a lot of clubs have as many spaces as us,there's very few at Everton and Liverpool and an hours wait to do the first mile coming home. Burnley, smaller crowd and pride themselves as a "friendly, family club". Paid £10 to use one of their disabled places, right next to the ground and not many of them, it took even longer to do the first mile. Went to book the next year and they wanted £20 for a Disabled parking space, we declined. Luckily, our club run the Magic Bus to all aways now. Chatting to visiting w/c users from other clubs, that's another thing only a few Prem clubs do and that includes all the Big 6.
Villa park, absolute gridlock coming out, if you use their spaces. We were in with their w/c users, not ideal but it was all good natured. Only 8 visitors w/c spaces, believe it or not, that's adequate for some Prem clubs, A.F.C.B. had sold them by teatime on the first day of sale.
Overall, I think our tinpot club compares well with others in the division. I don't think it can ever be perfect, after all, you're taking someone sat down on a wheeled chair, through a mass of thousands all walking tightly together. Then you're one of the first in your car but at the back of the queue when you want to move.
Our club does a lot of things right but, as in life. they'll never do anything perfectly
