You actually go to Guam? Is it pretty? It’s not one of those places that gets a spread in the tropical-tourism magazines!
I do go to Guam 2 or 3 times a year as part of my job. It is pretty, if not in quite the luxuriously exotic way that places like Hawaii are. There is also not much surf to speak of, and it's location is even more isolated than Hawaii's.
An eclectic mix of 1st and 3rd World is the best way to describe the place. I myself can only take it in small doses, as although the Chamorran people are some of the most earnest, kindhearted people you'll ever meet, the "island mentality" starts to get to me after very long.
Here in Japan where I live, people are very efficient and purposeful, whereas on Guam, you could probably call a fire department dispatcher to report a house ablaze and be told that a unit will respond just as soon as they've finished getting a cat down from a tree. "Hafa Adai isn't just a salutation, it's also a work ethic", as a common joke goes.
