I can confirm $50 GC offering for our April 9th tour. One of us is already a
DVC owner, so no GC offered. We stayed at Riverside, and they offered $50 GC.
Another interesting about FP+ restrictions that they offer for a tour- we tried to use it for Epcot character greetings and found out that we could not use it. Apparently, if you go to your My Disney Experience and click multiple experiences FP+ given from a DVC tour, it will tell you which ones that you could use these 3 FP+s for. Epcot character greetings was not on a list confirming what a cast member telling us about at the FP+ entrance for Epcot character greeting spot.
