According to Cruise Critic:

“Get beyond that, though, because of all America’s Caribbean islands, Puerto Rico offers the most exotic aura. The melange of indigenous Taino culture, combined with European and African influences in San Juan (and all of Puerto Rico, for that matter), is one major factor. Add to that its own unique influences in areas ranging from cuisine and music to history and art. And there’s more: folks who have traveled to Cuba say that Old San Juan reminds them more of Cuba, at times, than Cuba itself! It’s also very Spanish (think Seville) and even a bit Italian (reminiscent of Naples). Finally, the city evokes just a wee taste of South America (like Buenos Aires).”
