The family suites are in the all-star music resort. I've never seen them personally. But, last year my family of six stayed at art of animation... I believe the suites are a bit bigger at art of animation. You can google either to check out pictures and floor plan layouts.

Something else to remember, is that at all-stars you will be sharing buses with two other resorts. Which can be a major downer, depending on your travel time (higher attendance can mean LONG wait times for buses... especially at night).
