Hello. I have been to Runaway Bay 4 times the past 2 years staying at an all-inclusive there :-)
Where are you staying?
Weather is simple in most of the Caribbean during rainy season. Nice & sunny in the a.m., becoming cloudy and humid, then raining for a while and then being nice through the evening.

There is so much to see and do in the area--or nothing at all. From ziplining to horseback rides and snorkeling to rum factories--the area has plenty to keep you busy plus your activities desk at the resort will be more than happy to arrange things.
Ann, TS
