Okay, I have my envelopes here.
I paid in full August 8.
My DME packet was mailed out August 13, and arrived around August 19.
My "everything else" packet was mailed August 21, and while I don't recall exactly when I got it, it did arrive in a timely manner.
Now, compare that to last year, when I made my reservation through a TA (note: both years' reservations made the first day
free dining was available to the general public):
- I never got my 'everything else' packet. The TA called Disney, they said they mailed it out, told her where (my address, different zip), said they would send it out again. Still nothing. Called again. Same story. I called directly and finally got through layers of CMs to be assured that yes, I have a reservation even if the paperwork doesn't come. TA arranges with Disney for packet, with vouchers and luggage tag, to be waiting for me when I check in.
- I check in Friday night. They have no paperwork for me, other than the standard stuff, and WDTC is closed for the night. Come back in the morning. I come back in the morning. Nobody knows what I'm talking about. WDTC says they'll send it over and it'll be there Sunday. Sunday, nothing. WDTC says they can't do anything and to call Monday. By Monday, my trip is half over already

Monday, still nothing. Finally, a manager arranges to credit my room for a reasonable amount based on the value of the vouchers. I never did get the luggage tag (which is, really, the TRUE reason I booked this upcoming trip

)
- Also, obviously, no DME packet; must have gone to same non-existent location as my other stuff. Anyway, I called DME directly, and they FedExed a new packet to me which arrived a week before I left.
