When I stopped at a kiosk in Animal Kingdom and asked, they told me that they're not doing the tour incentives because they're only conducting walk throughs at the
DVC resorts. They offered us a business card with a QR code for more info online.
I toured Riviera on December 2nd and Boardwalk on December 3rd, and the only perk was the Riviera print mentioned above. It was basically just an open house walk through of the different rooms at the Riviera, and there were more than a few guides escorting groups before/after us so we did not have a long time in each of the rooms. There was also no sales pitch, they simply asked if we wanted to schedule a call with a guide for when we returned home from vacay.
The Boardwalk was not as busy, so we were able to linger at the lockoff they had open and talk longer with the 2 guides hanging out in there with the 3rd who walked us over. They leaned into the sales pitch a little more even after we told them we were already members. They had the Riviera print too, but we already got one the day before.
I set up a call with my regular guide, Summer, while touring Riviera, and after the call she sent me a $25 gift card for doing the virtual tour unexpectedly!
