Okay, I may be able to help a little here.
I priced a variety of rooms from Disney, both the rack rate and the
AAA room-only discounted rate. I added admission for 2 adults and one child using the advanced prices for 5-day expiring hopper passes. (We would buy a 10-day non-expiring hopper, though. See my note below.) I also called AAA to price the same thing as packages.
My prototype was a 4-night, 5-day expiring hopper pass.
By booking through AAA, you get those extra little perks like a pass for their comfort center, a "Diamond Parking Pass," and some other things that don't really have a lot of monetary value to us.
This is what I found:
PC-STD = Pop Century, Standard
GF = Grand Floridian, Garden View
Rack = Disney's Rack Rate + 2 adult and 1 child 5 day expiring park hoppers (including 11.5% resort tax, advance purchase prices)
AAAroom+adm = Same as above but using AAA rates as quoted by Disney
AAApackage = Package with room, tickets as above in rack, and the extra AAA fringe benefits.
(Ignore the _, they're the only way I could get the table to line up.)
Resort__Rack______AAAroom+adm __AAApackage
PC-STD__1010.14___938.78_________947.51
GF-GV___2223.26___1986.86_______1991.52
So the first thing to notice is that the AAA packages are close but are a miniscule amount more expensive. (I had done Port Orleans - Riverside, but I can't compare directly because AAA quoted a std room while I got my quotes for a water view room.)
The next thing I will point out is that the AAA discount (which you'd be giving up to take advantage of the free MYW Meal offer), is $17.84 ($16+11.5% tasx) for Pop Century Std, $33.45 ($30+tax) for a Moderate water view room, and $59.10 ($53+tax) for a garden view room at the Grand Floridian. Considering the Mail plan would cost $35 per adult and $10 per child, this easily beats the AAA room discounts. So for my family, this would be worth about $80 per night--if I get a postcard. For a family with 2 kids, it would be $90 per night.
But last December, the rates I was quoted with the PIN or BAT code for room discounts were $90 (+tax) for GV or LV rooms at the GF & Polynesian and a concierge room at WL, $101 for Courtyard WL, $87 for Wood WL, $80 for Std WL, $90 for Deluxe Savannah or Deluxe Pool View at AKL, $124 for Savannah View at AKL, $99 for Pook View at AKL, and $28 for Std Pop Century.
I'm not sure if tax is charged on those meal plan prices, but if it were, it would be 6.5% while the tax on the room discounts is 11.5%. So in terms of room discounts, the dining deal seems quite a bit better than AAA discounts and last year's room discounts on non-deluxe rooms. Compared to the last year's discounts on deluxe rooms, it's a closer call depending on the room and the size of your family. Who knows whether we'll see discount PINs or codes like we did last year, though.
Now for my note on admission. If we do this 4 night (it would actually be 1 night + 4) with 5 days of admission, we could buy 5-day expiring park hoppers for $666.70 (2 adults, 1 child) or we could buy 10-day non-expiring hoppers for $1019.21. If we did the latter, we'd essentially be paying $352.51 for another set of (non-expiring) 5-day park hoppers for 2 adults and one child -- about half of what we would have paid for admission for this one trip.
