We're a family of 5, kids will be 4, 7, and 9 for our first trip to WDW next year. It is hard enough finding an onsite room for 5, but I'm seriously considering inviting energetic, helpful, easy going grandma to be our 6th person, but that limits our onsite options even more. Budget will keep us at the value/moderate level. I'm considering CBR for 5 people, or AoA/FW cabins is as high as we can go. What would you do? Thoughts?
