So, I bought tickets to one day of a festival before getting pregnant. I'm 16 weeks and still planning to go and wasn't expecting any problem, but now they have said you can't take chairs in. I have the beginning of SPD (caused by an earlier pregnancy) and am struggling with standing for any length of time and sitting on the floor is painful/uncomfortable. I was just planning to take a chair. They have only just released rules in the last few days, which say no chairs and there is absolutely no way to contact them. Do I have any rights? Do I just argue it when I get there? What happens if they say leave your chair or don't come in?
