We have traveled frequently with extended family including my in-laws.
Each visit, we found it more affordable to book two rooms at the resort that fit our budget. We always requested connecting rooms on our reservations. While connecting rooms are not guaranteed, our request in the off-season month of January was always granted. When we traveled in June, our rooms were near each other but not connected. My experience is that WDW does their best to accommodate reasonable requests.
All
deluxe villa resorts will have two bedroom options, complete with a living area and kitchen. The best option will depend on where you intend to spend most of your touring time and whether a particular theme appeals more to your family. For instance, our family loves the Animal Kingdom Lodge for the theme and the Beach Club for the proximity to Epcot.
The All-Star Music resort is a value resort with a
family suite option. Other options for families traveling together can be found
here.
If space is more important than price, the
Coronado Springs Resort offers a two bedroom suite option. All deluxe hotels also offer suites at premium rates.
