August into October is also hurricane season. The last few trips I've taken have been late Sept into early Oct and I've been incredibly lucky to miss the storms ie hurricane blew through the week before I arrived and another time I flew out a few days before the hurricane arrived. While Orlando is inland and generally does not suffer as much severe damage as the coasts, it can still suffer some damage and dramatically up end travel plans. Many DIS'rs have cancelled their vacations at the last minute because of hurricane reports, often eating the cost of airfare and/or losing their vacation time at work, to avoid putting themselves and their families in danger. It's a great deal of extra stress in the weeks leading up to the trip as families decide if they will get on the plane or not. I'm not being a downer or trying to discourage anyone from booking FD in late summer/early fall, but just another important factor to add in the mix when you decide to book the FD promotion/take the room only discount for these dates. If you think the worry is exaggerated, search on the Boards for the threads dealing with the 2018 hurricane season. A great deal of planning, $ and dreams go into these vacations. Only you and your family can decide if WDW in hurricane season is a risk you are willing to accept.
