If your goal while on vacation is to experience "something completely different", then #3 is your ticket.

The first 2 options, while comprising fine holidays, can't compete with Venezuela as a 'magical mystery tour', IMO.

Full disclosure: I live near the Mexican border, so am already familiar with the language, history & culture there. Costa Rica and Venezuela I saw while on Army duty 20 years ago; my contacts with local people were minimal. Nevertheless, Venezuela was/is high on my "Wow"-o-meter. :)
