Me and 8 others should be going this year and hopefully camping, however one of us that is going is really not comfortable with the idea of camping due to a lot of anxiety around sleeping in tents with loads of other people around the area.

Ideally I'd like to make things as easy as possible for them, so I've been thinking that possibly I could get them a taxi back to my place (about 30 minutes away in car) every night so they don't have to camp, however I have no idea how simple that solution would actually be.

Last time I went to download was back in 2014 and we all got a lift there and camped the whole 5 days. So I'm wondering how easy it is to get a taxi or some form of transport every night.

Failing that, would any of the camping sites possibly have a more quiet area where they may feel safer?
My second thought is that maybe after the first 2 days they might feel safe enough with the group to stay if the area we stay in is quiet enough and not as crowded.
I know there is Standard, Eco and Quiet camping, but I suppose I have no idea what the sort of atmosphere is like in the Quiet and Eco areas, and if those may be a better choice for people with anxiety.

Side note:
The person going with us suffers from anxiety around people, but is wanting to attend download with us all because they want to try and push themself to do things outside of their comfort zone to hopefully not have it effect them as much in the future.

So anything I can do to make this easier for them and give them options would be useful.
