One thing people should never have to do nowadays in the Age of Information is overpay for a vacation or be lost as to what to do, where to go, to make the most of a vacation, or even make the most of the city they live in!
Tripadvisor shows you the top-rated hotels, restaurants, attractions, etc. for nearly everywhere on the planet, and the ratings are from users and travellers just like you and me. Not some company paid extra to represent! You can read real reviews on nearly every aspect and venue. The only thing is to take other people's experiences with a grain of salt but have common sense if several people have similar complaints.
Tripadvisor has, of course, all this information and more available for you to plan your vacation to Trinidad. So people wondering at which guesthouse or hotel they should stay, what to do in Trinidad aside from fetes, other people's experiences with all the above, plus relative costs (which must be verified at current and "CARNIVAL" rates by calling directly) can check this Tripadvisor link to Trinidad vacations.
Let me know what you think or if you found information on that site useful for your vacation planning!
