I've never stayed at Xtabi but I've been down in Jamaica a few times in early Sept and it is HOT! SO that said, I wouldn't get a cottage without AC in August.
Omg I totally agree. I’ve been there in September a few times and one time stayed at what used to be Catcha Gardens in an apartment with no AC. Needless to say I was miserable and a complete witch the entire time lol.
