We just booked our advanced DAS this morning and were able to book our entire 8 day trip, and were able to do the same full trip advanced booking for our trip last month as well. Guessing it was unique to the cast member you spoke with.
Well we got something, but not what we wanted. Blaming NPH's popularity for this! Glad we got something, but will keep checking. Frustrated I had selected exactly what we wanted multiple times but the site kept crashing before I could reserve it.
