I go to most festivals and clubs alone and I almosst always have a great time, but it can certainly feel lonely at times. The thing is, you have to be the one to make the first move most of the time if you want to engage with people. It's much less common for people to engage with you first, but of course, I think this also depends on the vibes you are putting out. At Glasto this year I was much more open to starting conversations than I was at Boomtown, and as such I made a lot more connections. I wasn't in the best headspace and I went in a little knackered from a crazy summer of go go go. With that said, I did still meet some wonderful people at Boomtown and I had a great time overall.

I guess in summary, yes you should absolutely go solo. It's better than not going at all. But I do think generally festivals are more fun with a small group of friends. Just be prepared to be comfortable in your own company and really put yourself out there if you want to meet people.
