Has anyone gone to Cuba ?

I've vacationed and worked in Cuba (drilling). Great country, awesome people for the most part. Food sucks at most places. I spent 5 days in Havana once and enjoyed that just about as much as staying in resort. Tons of history there, and at the time I lived in Costa Rica so the beach was a bit boring.
I would definitely recommend going at least once and definitely try to get a day or two in Havana.
Also, yes Americans can visit, it's only Uncle Sam who doesn't want you there. Book a flight from Mexico or similar. They don't stamp your passport so no worries getting caught.

Cheers
