It's just a space issue. So long as the reservation lists the dining plan online, or when you call, you'll be fine. I got mine the other day and it's actually cut off midway through the dining plan entitlements

. It lists the mug pretty high up, then lists a bunch of other stuff, the last thing is 1 quick service meal per night. (Since I'm the only one on the reservation, the list of names is shorter and allows more entitlements to be seen).
They really should have allowed it to print on a 2nd page, or the back of that Guest Itinerary page (which is blank) to avoid confusion. But it's Disney IT related stuff, I don't give them much credit in that department. (And, interestingly enough, Guest Itinerary is "Page 1" the backside of that page is... "Page 4"... I think they have some issues with the process that generates the packets

)
Erm... nm all that. I see the 2nd half of my stuff on page 3, which was hiding and didn't separate from page 1. So, really, ignore all that above. For those who aren't seeing dining plan info, check the pages on the packets, or just call to verify. I'm sure they're on there if you booked. (I gotta learn to look before I post

)
