We've booked a week in Barbados, staying in st James. all inclusive. We've 2 boys, 11 and 9 and I need to know the best things to do? Were all keen to snorkell ,any tips on where to go? Is it worth hiring a car for a couple of days-better to do it here or there? or just get a car and driver and any places where we should head off to? Any tips gratefully received.
