Keri:
There's a resort that your son will enjoy at Disney, no matter your budget. Here are my picks based on your son's age:
* Value Resort:
All-Star Movies. When my kids were elementary-school age, we stayed at ASM, and some of our best pictures were of them crawling on the statues of the characters near the Toy Story buildings. Although Disney doesn't guarantee requests, I'd recommend making one for this section. All-Star Sports also scores a homerun in my book for young boys.
* Moderate:
Caribbean Beach Resort. Upgrade to a Pirate Room and sleep in a "ship" bed! The weather in October will also be warm enough to enjoy the pirate-themed pool and its water play station.
* Deluxe: Animal Kingdom Lodge. Splurge for the Savannah View and enjoy watching the animals right from your room's balcony. This is a great fit if your son is an animal lover.
As for the parks, you'll find something for him at every park, but I'd give a lower priority to Epcot over the Magic Kingdom and Hollywood Studios with its emphasis on Pixar Characters and Star Wars. Animal Kingdom is a toss-up. If he loves animals and is tall enough for some of its rides, I'd put it on your itinerary.
Wishing y'all a magical vacation!
