I am off to Cuba soon. Flying in from Nassau and out through Cancun.

Would it be wise to just write at US customs the Bahamas and Mexico as destinations traveled to? I have 3 hour layover in the Bahamas, same with Mexico. I am nervous about writing Cuba however I won't be able to explain the gap between the Bahamas and Mexico if asked about that.

So basically better to be open about Cuba or why bring it up? (techinically my trip is legal as I am staying with Cubans and would be promoting democratic values to the Cuban people).
