We bought ours last night for Oct 16. This will be our first MNSSHP and our first trip for more than one day so we are really looking forward to this vacation.
We ordered ours by phone and was told that the tickets will be mailed to us and we should have them in about two weeks. Does this sound right to you all? It will be nice to actually get something in advance after having everything paid for for such a long time now.
There are two options to get the special party tickets, hard ticket mailed to you or Will Call pick-up at the Magic Kingdom.

If you have the ticket(s) mailed to you,
REMEMBER to bring it with you to WDW. We had ours mailed last year and I kept having nightmares that I left the tickets at home. I pre-packed my WDW bag with our Annual Passes and party tickets about two weeks before our trip ...

Note, if you do leave the tickets at home, Disney can look up the credit card used for payment and reissue the tickets.

I love getting Disney mail. The tickets will come in a non-descript letter-size white envelope (approx 4"x9"). So, keep an eye out for it. I almost threw ours away thinking it was junk mail.
The cards will be attached to a sheet of paper. You only need to bring the cards to the party. Confirm the party date printed on the ticket and that each ticket is for the appropriate guest (child ticket or adult ticket).

When ordering the Will Call option, print the confirmation sheet and bring that sheet to the Will Call window located at the Magic Kingdom entrance gate. The CM will issue your party tickets onsite. You can do this anytime before the party date, meaning even days before the party date. If possible, I'd recommend getting the party tickets from Will Call either days before the party date or in the morning/daytime of the party date. So, you are not wasting precious party time in line.

There is no paper print-at-home ticket option at this time. So, if you have a printed confirmation, that needs to be taken to Will Call to redeem for a hard party ticket.
Have a magical trip!
