Congratulations on your 6 days! Yes, I had to be very persistent as well.
Also, fyi: I bought tickets and got a Magic Your Way Package in case we wanted dining, and they were not able to combine all my reservations into one. They think there is something glitchy about the system since it's so busy at that time--they don't think it's that one of them was a package.
They told me to call back and try again in a week or so, so there's a bit of advice when putting all your reservations together (not that I'm sure what good knowing that is, other than to not be surprised if there are some glitches. I had four different reservations, so that's a bit of juggling!)
