First off, I can't book AK that far out, but we are personally partial to OKW mainly because it's quiet and you can pull right up to your unit and it feels more like home. Additionally, there's a really nice path walkway to Disney Springs which we like to walk. That being said, when we take grandkids, we stay at AK because they love seeing the animals. We like the quiet pools at OKW and the area in general. Plus the studios are larger as well. OKW is open Sept 4-14th while kidani is open Sept 3-15th. I will say for a magical experience, book dinner at Topolino's at the Riviera. Or dinner in Disney Springs at Morimotos or Chef Art Smith's Homecomin. Don't forget to see Fantasmic as it just restarted this past week. And the nighttime fireworks, laser shows are always amazing. If you decide to stay at OKW, let me know and I'll book it for you now. Otherwise, have a wonderful trip
