For our reservations this trip just past, we originally booked AAA, then changed to the AP rate when it came out. When a new set of codes came out, they saved us another $100 over an 8 nite stay! Hey, every little bit helps, so we changed to the code.
I don't think the AP rates will be better than the codes if recent history is any indication!
If I had to guess I would say the AP rates will be about the same as this new code. I talked to a CM last week who *promised* AP rates would be lower than anything else, but I don't know if I believe him. They just don't want us APholders getting pi$$ed.
I changed my DC ressie this morning and saved $600 for our December trip. We will be at the cabins at Ft. Wilderness from Dec. 18-28. I also have APs, so I will check next Monday to see if AP rate beats the code. I just don't think the AP rate can be too much lower. However, every little bit helps.
