We are family of 3 (2 adults and one teenage daughter) are traveling to Hawaii for the first time and know nothing about accommodations there. I am looking for a decent hotel or BB or special lodging that has an access to the calm beach for 6 nights in August. I'd like to stay on a budget of no more than $230 a night. A friend recommended Hilton but it looks like it's very expansive, and there is no real beach there. Just a lagoon. Maybe it's OK?
