Post in Gili Trawangan, West Nusa Tenggara, Indonesia

Hi there, I will be on Gili T from the 11th of January to the 29th.. I might couxhsurf for a night or two to meet some locals but then I was looking at finding some cheap accommodation possibly near Trawangan Dive centre, where I will be doing my dive instructor course... Any advice? And also I would appreciate any recommendations about good cheap restaurants where to eat vegetarian /vegan food, and things to do/see on Gili.. Thanks!
