Gill islands accomadation

Hey
So I'm off to the gill islands in a couple of days and am looking for a cheap place to stay with no bed bugs and that is I dunno kinda fun?
I'm not expecting it to be like kuta there but it would be cool to see some people maybe around my age (18).
So if anyone knows any tips they could give me please do!
And also some things that I have to see, eat, and do and what not while I'm there :)

Thanks!
