If you want to stay onsite, I would maybe get two rooms at a value. I would go to the Disney site and plug in your dates. I played around and came up with about $4,600 for a week at POP (2 rooms) for 2 adults and 5 children, 7 days of tickets and quick service meal plan. You can ask for connecting rooms. (they are not guaranteed, but very possible) This did not include airfare. This is with no discounts, you could possibly get a discount for that time.
