$200 should be plenty, just make sure you don't go overboard by not watching costs. On my last trip I didn't bother looking at how much I spent, anything I wanted I just bought and whenever I had no cash I just went to the nearest ATM. I ended up spending about $310/day for 14 days. My trip before that it was $84/day for 14 days. The difference was only the number and quality of TG's I had and slightly better hotel rooms. Thankfully on my last trip I had a digital camera to remember the fun times
