Is Download Festival accessible for us?

Hi my name is Ruby and I am 26. I love music. I go to as many gigs as I can to see my favourite bands and artists. I can manage gigs because even though it's crowded, it's only for a short space of time, and the pay off is worth it. I tend to try to get there early and leave early if I can to avoid the crowds. I can go home to my own bed. 

I have never been to a music festival. I have always wanted to go to one. Every year I get FOMO when I see people posting on social media having gone to one.

This year, the line up for Download festival looks fantastic. I'm wondering whether I should give it a go, but there are lots of potential issues I'll need to consider. It is important to note that I would likely go there on my own.

I struggle with crowds, noise, and mud, so not off to a good start. The feeling of being dirty is horrible. I would ideally need to be in one of the quiet areas and would want to stand somewhere I can escape easily. 

I've noticed Download says they have a disabled campsite area. Has anyone here had any experience of using this? I read an article online that the disabled area wasn't as accessible as it claimed to be. Does anyone have any advice on what to look into in terms of what accommodations they can provide? I am trying to work out whether this will be feasible before I even decide to buy a ticket. If I decide there are more cons than pros (there are a lot of bands playing which I would love to see Live), I'll just stick to going to gigs where I can get the train home after. I've looked into their VIP packages as I think I'd find that a lot easier than camping, but most of thier packages are for bigger groups of people. Any advice would be appreciated.
