I would go to Japan. In the USA they seem to think Cuba is so exotic because they don't go there... but everybody else goes there. In eastern Canada it's a very popular spot and I know people who have been half a dozen times in the last few years.
I just looked up a flight... you can fly Toronto to Havana and stay for 7 days. Flight, pickup at the airport and hotel. It was under $400. I guess that's why everyone goes there.
I plan to go myself.... I'm just waiting for my next batch of test cameras from Sony and I'm out the door. To me Japan would be more exotic.... but too costly if I'm just testing cameras.
