I always made it a point to limit my power drinking to one night there (usually the last night before leaving port....always much easier to leave land when you are hung over) in whatever country I was in, and the rest of the time was dedicated to getting out and seeing the land.
I hit 31 different countries during my time overseas. Loved the traveling....still do. Always made it a point to try eating local meals as well. Never understood the guys that traveled half way around the world to go to McDonalds. Just mind boggling to me. Don't get me wrong....get one while you are there if you have a hankering.......but hell, get out and try some real Thai food or real chinese food or real japanese food or the real deal sushi.
Remember those seafood markets in thailand where you could buy those prawns that weighed like a pound a piece? Man I made it a point to hit those places and chow down. Thailand was the first place I ate octopus. I had squid before, but never a full on octopus tentacle with the big suction cups and all. I tried all sorts of crazy shit. Monkey, dog, cat, giraffe, zebra, croc, snake, insects.....I even tried that damn duck egg thing that Pinos love. I puked my guts up, but i tried it LOL. Don't try it....its gross.
