October appears to be cheapest from the UK, but, hurricane season, I'm not chancing it. November suits us down to the ground- it's still one of the cheapest months, great bunch of people go every year, weather is warm enough for us, and on returning home there's only a few weeks before we get a break from work at Christmas, so don't get the post-holiday blues as bad! Only downside with the winter months is the sun sets early, so party at the pool winds down around 4pm. To be fair, that gives us a few hours respite before the madness kicks off again at Paty O a few hours later!
I must say that June has never disappointed us. It's warm and sunny during the day. Everybody gets in the sexy pool. The evenings are still warm enough for the ladies to wear very little clothing and look HOT!! The sports pool is perfect to end the night off in June. Perfect temperature, plenty of sun, and a lot of sexy hot people to party with!!
