Yeah, in my younger years I was all about seeing as many places as I could. These days I tend to hunker down in a few spots more.
Both strategies have some merit, and not just on vacations. I'm a big believer in trying a little of everything at the start, because as Donald Rumsfeld would say, you don't know what you don't know. I call it my Buffet Strategy. Put a little of everything on the plate the first time, see what's good, and then when you go up for seconds you dive in to the few dishes that really satisfy.
The Buffet Strategy works for everything--vacationing, beer, porn, hunting, chess, fishing, sex, pop tarts, cars, women, literature....you name it. Except for children. Unless you're Shawn Kemp, you generally have to stick with the first couple of those you get.
