If you care about Cuba and its people, do not go there and fuel their corrupt economy with your tourist money. Cuba needs a revolution to bring it up to speed with the rest of the world.
If you don't care about Cuba, then go and see a unique culture the likes of which will never appear in this world again. You will not be disappointed if you go.
