Overwhelmed by the possibilities?

I am trying to plan a low budget trip to Hawaii and I am completely overwhelmed with all the choices. Our family is not very commercial and we like cute bed and breakfest inn’s. We are willing to spend money on kayaks and things like that but we don’t mind simplicty like hiking so any good hiking areas would be good. There are six of us and we are trying to go christmas time to a little past new years. So ideas? Any of the islands are fine just remember non-commercial and low budget.
