It sounds like travelling society will be a good idea. Though it’s daunting that you don’t know anyone, I’m presuming that usually the type of people travelling society attracts are ones very open to new friendships. Even people who have established friend groups should be willing to expand their circle, If you walk in confident in being alone, people shouldn’t bat an eyelid or judge you for it. Also, first years will definitely be easy to talk to as they won’t know people super well yet. Even if they know at least one other person there, ofc people will want to get to know more.
