Actually, the answer is no. We are booked 3/25 to 4/1 and had the code applied to our reservation at CBR.
We have 2 adults, 2 kids, 7 day base tickets, basic dining for $3,095. Down from $3,430. It did not work at first because the CM was applying the incorrect code. We needed code KNM applied which is the code for a stay at a moderate resort with dining plan at seasonal pricing.
I would call and check.
