16 eh? Wow, well if you have the chance take the trip!
Yes, bring plenty of it if you plan to wander around outside. Some places are worse than others of course but generally speaking it's a wise precaution. Taking a boat around the coast is great fun if you have the cash. Of course, the "touristy" things only offer so much entertainment. What's really fun is to hang out with the locals for a while since life there is so radically different than nearly all the US (and thus so are the people). It definitely makes the trip memorable.
