I was able to change my rack rate reservation at WL to get the AP discount by splitting my reservation.
We arrive Sat Dec 4th at WL and will switch resorts on Wed Dec 8th to Pop. I was able to get the AP rate for Pop when it first came out but no luck at WL. Then last Thursday when I called to see if by chance any discounts were available the CM said no, the weekends are very busy. A light bulb went off in my head! I asked the CM to check if the rate was available for ANY part of my stay - AND IT WAS - courtyard view at $137 per night for Sun, Mon, and Tues!! The downside is that we have to "check-out" of our Saturday night room because we now have two reservations for WL. The CM suggested upgrading our first night stay from a standard room to a courtyard view room to reduce the chance of having to physically change rooms.
So, we now have the first night at WL courtyard view at rack rate, and the next three nights at the discounted rate. Overall we saved $120 and now have a courtyard view!!
We saved a total of $245 with the AP discount this trip!! Of course Disney is going to end up with that money anyway, but now we get to decide if it is going to be more souvenirs or another nice dining experience, or.....oh the possibilities!!
