Also based on 20 years ago, but still should be good…
By law, all beaches are public. This means that although staying somewhere else, you can rock up at Sandy Lane in a tatty rented mini moke, amble through reception, and plonk yourself on the beach in front.
As above, public transport is a good alternative to car hire or taxi. There is official public transport which is fine, and there are also reggae buses which are cheaper, more crowded, and … louder. I know which I prefer.
Hurricane season. Well, it is a risk. But most years, and most weeks in even the worst years, Barbados is not hit by a hurricane. However, it is likely that it will rain sometimes. When it does, the sky really does fall in. 20 minutes after is stops there is no sign it ever rained.
Food. As almost everything has to be imported, self-catering is expensive and a pain. As above, much better to use the local restaurants.
It is quite possible to find ‘deserted’ beaches, if you have transport. If someone appears and offers you a fresh coconut, he’ll want paying. Agree the price first.
It is a very chilled place.
