There is a bit of information in the comments at the bottom of this blog post: http://boardingarea.com/blogs/onemil...rad-koh-samui/

I think the summary is- no nightlife near there, there's an off-resort restaurant or two near there, one is called green talay.

We rented a car there last year when staying at the W Retreat. The rental isn't really cheap, but we still more than made up for it's cost by not dining at the resort at least once each day. It was pretty liberating to be able to pop out to Tesco whenever we wanted to stock up on food/adult drinks. Didn't find driving there particularly stressful, just have to watch out for the crazy number of motorbikes.

Heading back to BKK tomorrow and Samui a few days later. Can't wait!
