Why spend a week in Easter Island?

I've wanted to visit Easter Island since I was a little girl.  Fascinated with the mystery, remoteness, and history.  When I read the various blogs and online tips about what to do, where to stay, it all seemed so rushed and forced. Filled with highlight tours of the main historical sights of either 3 days/2 nights or 4 days/3 nights left little time for activities, exploring the island, or immersing yourself into a way of life.  More like scratching off a to do on some planned bucket list.
