Defo different strokes. The taxi thing wouldn't appeal either, as that would still tie us down to relying on public transport, plus I'd love the sense of adventure/thrill of driving a car in a country I'd never been to before, and going off the beaten track! Exploring, for us, is essential.
We like to mix with the locals, and go into small towns/villages and get a REAL feel for the country and its people - especially the food! I'd be wanting to find some little restaurant, tucked down a side street, full of locals, serving the most amazing traditional Caribbean dishes, and most likely for buttons...
Rarely, when we're anywhere (apart from on city breaks for a long weekend) do we do the tourist thing, or for that matter go full board in hotels - always just B&B, so we can choose where we want to eat for our main meals, often somewhere we've discovered whilst out in the car.
Wherever tourists are, especially Brits [as the type you meet abroad tend to be nightmares], we'll go in the opposite direction!!
Enjoy Barbados, when it comes, mate. I'm sure you'll have a great time
Marco.
