We did the tour at
Disneyland in 2015 and received three Fastpasses each (there were two of us; there were some restrictions on it. Maybe not valid on RSR and Peter Pan?) and a $50 Disney giftcard.
We were staying at the Disneyland Hotel so had walked past their kiosk in Downtown Disney and my dad stopped and chatted with the guy once (I was off on a park tour). When I got to the room later my dad told me about it and said I should go sign us up for a viewing. I planned it so that it would be late morning/mid-day when we would want to be leaving the park for a break. We took the monorail to DTD and the DVC building is practically straight in front of you. Got to sit in aircon with snacks while we saw the presentation and received the aforementioned gifts at the end. We were in the parks for 5 days, so had spare time to give to the tour and didn't feel like we missed any of our break/park time.
