Try Alpharooms.com its a travel company based about 40 miles from me in UK. Sometimes we get better rates here than you get in US. I use them for a lot of my trips and recommended them on here, nobody has had problems with them as far as I know.
I only did a quick search but 2 that stood, first was Courtyard by Marriott LBV its a stones throw form Downtown Disney, stayed there 25 nights last August and going back again fro 25 nights this August, great reviews on Tripadvisor $69.55 incl tax.
Another is Homewood suites by Hilton International drive, larger than your average room, $81.82 incl tax and breakfast (decent breakfast we enjoyed it).
They have lots more from $33 incl tax. Allstars Movies for $101.
Hope this helps
