HI, and welcome!
I've never stayed in any of those resorts, so I'm no help to you there. But I LOVE Disney in August!!!!
A few things that helped make those trips so much fun:
- The meal plan! We've enjoyed so many wonderful meals at WDW!! It's not about the food, it's about sitting together as a family to stop and talk about our day AS we enjoy the great food and terrific atmosphere. For my family, at least, it's a savings and worth every dime. And food can be expensive in WDW. If my numbers are correct, the meal plan will cost the 4 of you about $110 a day. That will buy 3 full sit down meals (including character meals) 3 counter service meals, and 3 "snacks" -- read that as a bagel or croissant or other breakfast food. Your little one can probably fill up with odds and ends from what the rest of you order.
- In the past, we've brought at least one small stroller. And there were times when my older daughter, at age 6 or 7, was the one in the stroller (usually as we headed towards the resort at night) while we carried her younger sister.
- We get to the parks every day before they open. The first time, it was "shortly after opening." Nope, not good enough for us any more. "Before opening" is key.

amazon and get a Misty Mates personal mister or two. They're lightweight, take up next to no room,don't require batteries, and make those hot humid August days so much more bearable!!!
- Plan to go back to your resort for a swim and/or nap every day. We get to the parks for Rope Drop, spend the morning doing the park, then head home shortly after lunch. We then return to the parks for dinner and the evenings. Afternoons are brutally hot and crowded.
