If you want more than a hotel room, try skyauction for a condo rental(ready , set, go auction). Last year and this year, I got a 2 bedroom/3 bath condo for $250 for the whole week(taxes and fees included).
I have seen the Courtyard by Marriott for $20 mentioned on this board(but this did not fit in my vacation time)
Since we had the kitchen, I bought breakfast stuff that we ate before we left. Packed a bunch of snacks/pb sandwiches to take to the parks, so we did not really have to buy much there. Only meal out was fast food for dinner.
I got really lucky on flights and only paid $84 pp round trip from Milw(not including fees) and a cheap rental through Americar(not the greatest place in the world- I got what I paid for).
We skipped the souveniers, but this year I am prebuying some Disney stuff from my 99 cent store.
The only place you can't really save much money is on the park passes. If you know you will be back, buy the most days you can, and use up the rest next time. Maybe plan some pool days to save on the park admission.
Some people may think this is too much, but it did not bother us. I did not mind staying off site. I preferred the extra room over being cramped in an All stars(they won't even let you put in 5 people anyhow, and we have 3 kids). The kitchen at the condo was great- Disney charges $10 bucks a day just to rent a fridge! Driving from off-site did not take us very long- I think the busses would have driven me nuts. the downside to driving yourself is the parking fees.
You could drive to save airfare/car rental. We might do that next year after we get a new van.
Go off season if you can- cheaper rentals and you can see more in less time.
have a great time!
