Bora Bora is spectacular. Everything you ever imagined about a South Pacific island paradise -- Bora Bora is it. I'm not into exxxtrrreme sports or hoppin' nightlife -- all I wanted to do is laze around the lagoon. We did rent bicycles for a day and ride around the island -- it's about 20 miles, easy riding.
About the expensive incidentals -- yeah, they are, but compared to the cost of your overwater bungalow they're probably not that big of a deal. Bring what you can, but don't sweat it if you forgot something.
