Definitely do it ;-) I had one month experience on island Java and I had fabulous time there! Few days I spend on Bali and it was quite different... people on Bali know how business work... for example we hitchhike on Java and people make photos with us, when we hitchhike on Bali, they asked us how much ;-) but not all population in Bali see in us just money. Everytime, everywhete it is about people :-) Bali is maybe more comfortable, because it is small island with lot of nice and cheap accommodation. Enjoy day ;-)
