My mother booked for the last two weeks in March. The second to last week was good, but the last week was tight. She got $109 AP rate at the POFQ, but some others weren't available. They're starting with 4-nts WL then 4-nts AKL, but they couldn't extend AKL beyond that and BC was $439 (Yikes!) so they went for POFQ.
You can check availability anyway at WDW official site.
