Hi Scherron!
I'm all for you booking your Walt Disney World vacation at Disney's Port Orleans Riverside Resort. Full of beautiful lush grounds and oozing that southern charm, one may be found whistling Dixie when they stay here.
From the perspective of a Mom who has traveled every year to Walt Disney World during the latter part of the August month, I can say that it is a wonderful time to visit. Guests are still able to take advantage of that awesome summer sun, as well as lower crowd levels, due to most kids in the US preparing for back to school. Late August (last two weeks) is also a prime time for Disney to release a special offer for guests to take advantage of. These offers range from room discounts to the coveted free dining offer. Historically, there has been an offer released for this time period every year for the past five years, so the probability of that continuing is good.
My best suggestion for you is to keep an eye on the
special offers page of the Walt Disney World website to see the current promotions and take advantage of whatever special offer may come your way.
Hope this helps you plan your magical vacation!
