We have 4 kids, too, and we have done several things. We stayed at the All Stars in 2 rooms, and having the 2 bathrooms was a plus. The drawback: the rooms are very small, and the room my DH and I shared had 2 double beds instead of the king we requested(king is not guaranteed). DH said never again! We have had connecting rooms at Coronada Springs as well, and the rooms were a little larger, the pool area a little nicer, but again, 2 double beds in both rooms. I know they have king rooms, but they charge extra for those, and I don't remember if the king rooms connect to a room with 2 doubles. DH said maybe do that again. Then we discovered DVC, and have been spoiled ever since. With a 2-bedroom, we have 2 bedrooms(king in 1, 2 queens or 1 queen/1 queen sofabed in the other),2 bathrooms, AND a full kitchen(that we don't always use). The only drawback:the 2-bedroom costs a lot of points. If you could rent points from a member, you may find this the best option. If you are planning to drive or rent a car, I suggest staying at Old Key West because you can park right outside of your room, and getting to the parks is very easy. If you will not have a car, the VWL may be your best bet(I am assuming that you will want to spend more time at MK than anywhere else) because the boat can transport you over. The cabins would be a good choice, too, because you will have a kitchen and they can accomodate 6. The only drawback: 1 bathroom(may not matter since 2 kids are very young), and the transportation seems to be hit or miss at Fort Wilderness(I have no personal experience to share). The best thing to do would be to price all your options and decide what luxuries are worth paying for. I wish you luck!
