neighbor island travel

Hi! 👋🏿 ok so I'm 23 and I live on Oahu! And it's Summer!! Just a few facts to consider with what I need advice with. Anyway, I work so hard and I want to travel but I can't do too much! So I was gunna go with someone but they're all talk and no DO! I know plans change and things happen but when i say I'm going to do something, I'm going to do it! So I've been looking into going to the Big island and I really wanna go but idk if it something I should or can do in my own. Financially I can..... so maybe that means I should do it huh? Idk thoughts???  Thoughts🤔 💭
