Ok, not easy, well, my advice is get a quechua tent and sleeping bag, now is warm, u can try casa de campo every night then back to center, also work some extra hours on hostels exchange of acomodation, many places around the world are going crazy with reanting, to pay, etc.

Thats why u can just travel wiht little amount of money. Try the pubcrawl company, they looking for people to promote parties and give some time bed on hostles at same time u can practice ur game.

If u need more deeper advice I can try do a videocall.
