Can I get some creative ideas for what I should do in my vacations?

I need some ideas for some creative things that I can do in my vacations. I don't have many friends so tell me things that least require partners. I am a self learner and can learn and do almost anything by my self for example I learnt to sew, play keyboard and much more by myself. I am a computer geek too so I can do things related to it too. Tell me alot of creative things that I can do. even if its related to art. but not like go to the beach cuz that requires me to have friends and its not creative
