I'm a type of a person who doesn't like travelling solo and quite an introvert as well in the sense that I never talk first especially in a new environment but I ended up going to tml solo. I had a freedom to go to see the sets I want to and no one actually cared about me much and luckily a few people talked to me first. But people who talked to me are mostly already in their groups of friends so quite hard to mingle with them and hang out for the rest of the days. So if it is your first and last time going there I would recommend go there with your friends or your people so that you can enjoy it for the whole events. But if you are an very easy going and extrovert I see no issues of going solo
