mamanucas, near yasawa's... where to stay

Hey there,
am off to fiji at the beginning of july,
just looking for some recommendations on where to stay or where not to stay in the mamanuca island or the closer yasawa's

looking for nice beach, good snorkelling right off the beach,

somewhere kinda quiet, i.e. not alot of kids/families and not alot of young drunk backpackers, lol

looking for a double bure, under 200$ a night

thanks
