We're looking at going here in summer but having got DH's agreement am nervous about weather. St Lucia in july when we went before DS had quick rainshowers and only 2 days at most with more in 14. I thought antigua was less humid and drier. But am going only on google - which of the above times is likely to be better - is August cheaper for good reason?!
Also any ideas for reasonable hotels but with fab beach and decent food?
