Sorry bumbershoot....you are the AP guru.
To the OP, one thing to keep in mind, even if you book w/o AP, keep checking back with DLR Reservations (or here) over the next month to see if the AP5 rate opens up for some or all of your dates.
If it does, you can pull the trigger on ONE AP pass at that time.
(What's the AP5 rate on the GCH? Got to be ALOT less than the $384 discussed.)
Why, I outta....
Looking yesterday at the Hotel Calendar on the AP site, which
says it shows the best rates available for AP holders at that time, it was 360 at GCH (if memory serves).
But it really does change...I've said it before...there was no really good rate for my one-night stay last weekend until I checked 48 hours out, and saw a 139 rate (at PP, not GCH) that was tempting. It wasn't there until between 48 hours and a week from my trip (I hadn't checked for several days). Things do pop up!
So with the deluxe, if you're making up a $33 difference, that's $330 worth of food assuming you only buy it at places that offer the discount (so no Brrr-Bank ice cream, and in my experience no Royal Street Veranda). Do you think your family will eat $330 worth of food in those days?
If you haven't seen them, check out the menus and prices at allears and dlresortinfo. That will start to give you a good idea of prices. Since two of your munchkins don't need to pay for their food (one would assume the 5 month old's needs will be taken care of without disney's help, LOL, and the 2 year old can eat from your plates) it is a good question, especially if you're not doing character meals, etc.
I definitely agree with Hound 109, that you should keep checking (ask one of us to check or just call).
OK, interrupting myself. I just noticed that while the Standard room is listed on the AP site right now at $360 for the 29th, the View room is listed at $328. OP, you may wish to call for that.
(714) 520-5006 from 8:00 a.m. to 6:00 p.m. PST daily to reserve your room. Please ask for rate plan "AP5.
Before I saw that I was going to say that I love
AAA, but I already belong. I see AAA as help with car issues, and all the travel stuff is just extra.

And I'm not sure that you get the discount in as many places as you do with the AP. I could be wrong on that, though. And since you are traveling during the time that the AP5 *can* be valid, and the AP rates *can* pop up and get even better...know that the rate you might be getting could be far far better than the normal AP or the AAA 10% discount.
