I just got Pop Century for $79.00 per night + tax, standard view, 2 nights April 16 & 17.
No calling, no holding.
I booked at disneyworld.com with their Winter Offer link. I had to pay my deposit immediately and I have to cancel 46 days in advance to get my deposit back, but if AP rates do come out for that time, hopefully it will be well before March 1.
