Welcome to posting.
In 2015 stayed 2 weeks in Yacht Club from July 4th - bit hot and humid but OK. In 2017 stayed 3 weeks in Beach Club excellent weather just before hurricane struck 2 days after scheduled departure - Epcot Food and Wine was great especially as BC just round the corner from it. This year aghh! Have booked (April 2019) for 3 weeks at BC from 2nd September as wanted to do the Halloween Party and thought we would risk it with the hurricane possibility. Still waiting to find out what is going to happen - borders may open here (Jersey C.I.) in 2 weeks but will US be open, will my flights (2 to get to Florida) be running. It is quite exciting. I can recommend end August beginning September as there will be more events happing Where are you planning on staying?
