There are suites in most of the Deluxe disney properties but I believe most of the two bedrooms only accommodate 8. You may want a combination of a suite with another room next to it. My family loves the Boardwalk and have stayed in a 2-bedroom villa there, very nice. I would personally rather stay in plain rooms in Disney than outside, it is just such a different experience. The all-star music also has 2-room family suites very reasonable. I have a wonderful authorized disney travel agent - she is great and has always found me great deals. I know there is the free dining promotion in September. She is compensated by Disney, not you and has such great first-hand knowledge - If you would like, email me and I could send you her contact info. She even does a full itinerary at no charge!
