Check out Bonnet Creek Resort through Ken Price at vacationupgrades.com.
Beautiful resort next door to the Caribbean Beach Club. Multiple pools and lazy rivers and free mini golf for the kids.
This! We have stayed on site SO many times...then we tried Bonnet Creek. Now we're hooked! We we are booking again for Christmas with Ken.
Also, another really great option is Hyatt Regency Grand Cypress. Tons of free activities for the kids, wonderful atmosphere for the adults, and it's right around the corner for DTD. It can be pricey, but if you can find a good rate through Expedia or somewhere like that, it's very worth the snag.
