I`m not a guitarplayer myself, but I know someone, who took his guitar on an IR-trip, some years ago. His intention was to sit beside a romantic fire, with a nice girl at his side, and to play some songs for her. At least, he thought, it would attract the girls if he would play the guitar.
He finally came back without the guitar, because someone broke it on a train. He said he had put it in this baggage compartment above the seats, and some other guy put his bag beside it. When he wanted to get his bag to get out of the train, something got stuck to the guitarbag, and he pulled down both. The guitar crashed on the top of a seat and broke.
He also said that he found it annoying to have to lug it everywhere, so he would not do it again.
So, maybe you should start to sing. If you run out of money, you can sit infront of a supermarket/warehouse/mall and sing. If you are good, the folks will give you money so that you will continue, if you are not so good, they will give you money to make you stop
