Same thing happened on our reservations this year made in August for a December trip. I made a resort reservation for myself and hubby and a separate one for daughter and her boyfriend, both online through my Disney account. I input full addresses on each reservation and the confirmation emails showed the correct addresses. Within about a month I received the info booklet from Disney Destinations, LLC at my mailing address for my reservation. I waited to hear from my daughter telling me that she received hers at her address.. and waited... and waited. After some 3 weeks, I called Disney. The CM I spoke with said she couldn't see why my daughter didn't get HER booklet yet although she did say that Disney sometimes combines mass mailings by states and since my daughter and I live in different states, there may have been a "significant period of time" between the mailings for our two booklet mailings. I told the CM I was concerned because the missing brochure may indicate a problem when they do mail out the "important" shipments of the travel documents and the magic bands. I had her doublecheck the mailing address of record for my daughter's reservation and it turns out that their system dropped the "apartment number" from the address even though it was completely and correctly listed on the reservation confirmation email I received. She went ahead and added the apartment number to the address and I had her "test" it by requesting that they send some mail - any mail - to the now complete address for my daughter. She spoke with another CM at the appropriate unit at Disney and had them initiate a forced mailing of that info booklet. She said the mailing would be sent 7-10 days from the request, and I noticed that based on the date information on the envelope of the booklet I received, the booklet was received by me a week after the listed "mailing date". So I figured if it worked, my daughter should receive the newly requested booklet in about 2-3 weeks. A review of my texts with my daughter shows that I spoke with the CM on 9/4 and my daughter confirmed that they got the booklet 9/21. The apartment number they added to the system was "off" as the CM put an "8" instead of "A", but the mail did have enough of the correct apartment number to make it to their mailbox. I called Disney and had the CM make the letter change so all should be good. It may be overkill to do this just to get what is essentially a promo booklet, but the chance that the no-show of this booklet may indicate a problem with them being able to get the travel documents and magic bands promptly and efficiently to my daughter later made the worrier in me want to check with Disney. So it may be worthwhile to verify the mailing address for the reservation with a CM if you didn't receive a booklet, especially if you have a long address, or one that is often misspelled, or in my daughter's case, an apartment number that the Disney system chose to simply drop from reservation confimation to entry into the system itself.
