How awful for you to have to change resorts, but I would have done the same when my kids were that age!
Although I have not checked availability for your dates, they do fall within the time frame of the email pin number- assuming we recieved the same one recently! Here's the rates I was offered when I called (not including tx):
WL - $134 - Courtyard view
Cont - $149 Garden Wing
Poly - $209 Garden View
Beach Club - $209 (only 2 nghts)
BWV - $209
POFQ/ POR $79 garden and $94 water
CBR - same
POP - $49 standard, $59 preferred
Maybe you could switch to the WL? Those rates are very good and you'd still have water shuttles to the MK and FW for the Hoop-Dee-Doo - if you're doing that this time. It's a tough decision to change to a moderate, but I'd be considering the same based on the great rates you had for the AKL. It's a big jump to the Poly or EPCOT resorts.
As some have said, the size of the rooms of the moderates and AKL and WL are not that much smaller . A bit and you might feel it, but not like a value - which would be tight for 4. Some say the CBR rooms are a bit larger. I've stayed there as well as most of the moderates and deluxe - it did seem a tad larger than POFQ, but I could not swear to it!!
Sure hope something comes through for you soon!!

p.s. we've never rented a car and have used Disney trans sicne 1982 - never a problem - ever! We go back to the resorts during the day for a swim with the kids or nap or just to hang out for awhile. Very relaxing without a car.
<edit> Tikiman, your Poly website is incredible! It brought back so many memories that I dumped my budget worries and called tonight to change my res to the Poly. Great rate of $209 for 9/27-10/2. All the longhouses have new names since I last stayed there, but I requested 3rd fl, Tahiti or former Ohau.
