Where should we locate ourselves?
It's hard to describe which is better but easy to mark the differences. English Harbour
is the historic centre and it does have some nice places to go out and eat in but I have to say I prefer the restaurants of Jolly Harbour. The bars are harder to see a winner though out of season Jolly Harbour seems to be busier. As far as attractions goes there might be a dead heat here, many are located close to each location and others further afield. But luckily nothing is too far in Antigua.
There are boats in both English Harbour and Jolly Harbour, I think the historic beauty of English Harbour is nicer to look at but jolly Harbour is also beautiful in it's own right. With better beach options Jolly Harbour wins.
There are some really great vacation rentals in both centres. Jolly Harbour
has more beachside villas to choose from however.
The answer is not to sweat it! Enjoy what is around you as you will and make the choice of location less important than what you need from your villa. You might also choose some of the other locations such as Galley Bay Heights for your luxury villa where you will have to spend 20,000 for a week rubbing shoulders with Giorgio Armani as he could be your temporary neighbour.
