You can’t just fly into Cuba, one travel expert told me. You need the proper authorities to get inside, I read time after time on the internet. My own Florida-based travel agent insisted even with the eased restrictions it was impossible for Americans to stay at Cuban hotels. The best way to see the country, he persisted, was on a cruise. Turned out, they were all either lying for whatever reasons or grossly misinformed. The proof, as they say in Cuba, is in the pudin.
