Preview is one of those "refreshing alternatives" everyone seems to be raving about these days. Hanging by the pool with buds and beer (sorry about the alliteration) made the walking seem that much more worth it.
Listen, bugger all these fancy places. The best place (not to mention the cheapest) to chill out with a beer has to be Stavros's "bar". If you can get to the glass bottom boat tour, turn around and you'll see a man sitting amongst 25 or so lawnchairs, with one fridge in the room behind him. He's the coolest guy in Argostoli, and when the girls went shopping, my friend and I stayed and enjoyed the step back from life. (now THAT was poetic!)
