I would say that the All Stars are your best bet. You can get one of those great rates they have for about $50-60usd, depending on when you are going. The biggest advantage is the transportation included. The rooms are just okay.
If you get one of those real cheap rates in the hotels around Lake Buenavista and near Hotel Plaza Blvd. which in my opinion are your best choice off propeerty, you will have to add a van to accomodate all your party and be able to go to the parks when all of you are ready. Some of those hotels offer free tranportation to the parks, but the buses run on certain times of the day only, so you will have to adjust to those times or pay for a cab that in Orlando is very expensive.
If you have the Disney free transportation from your hotel (staying on property), it runs continuosly, so if half of your party is ready, they can start the day or end the day earlier, you get the idea. Carry walkie talkies... they could be useful.
If you don´t find a good rate for the All Stars when you are going, check with the Holiday Inn Sunspree Resort and get a van... don´t rely on transportation from the hotels. The hotel is very near to the parks and it´s excellent for kids. There is (or used to be) a 7Eleven next door, gas station, Wendy´s, IHOP, etc., so meals can be cheap and you won´t have to eat that much at the parks where it can get real expensive. A good big breakfast can save you from an expensive lunch, and then you can snack a little until dinner time out of the park. I think the Holiday Inn (or the other off property hotels) also has a kitchenette, so when you put it in a balance, it could get a bit less expensive than staying at the All Stars. I haven´t checked, I´m just thinking about it right now. :animwink:
Good luck with your decision!
