True or false.....

According to Boston.com, the wee isle of Nantucket is "a posh island resort".

Dear readers who frequent the lil' rock o' Nantucket: is this true?

Or would you say this is false?
(about the posh resortyness of it all, I mean)

And before you decide, please note that the following movies are set in a "posh island resort":

I Still Know What You Did Last Summer
Evil Under the Sun
The Marine 2

You see a pattern here? I surely do.
