Ill say this based on what I know:
ADRs at 60 days staying very likely
Dining plans back- Once at full capacity- likely back but with new guidelines and some added verbage to protect WDW
Oh and FWIW,
FREE DINING- Dont call or chat a CM and say something stupid like "will I get a refund on the free dining I paid for?" It made me shake my head and laugh out loud when I heard that yesterday.
FPs- Once back at full capacity- A whole new world that same day refreshers will have no problem adjusting to but others may not like. ( Some people will hate whatever they do anyway). AND this could be the time they implement some sort of paid system in addition to the already free FPs. Lots of things going on with this right now
Hopping- Once back at Full capacity will come back but in a slightly different form. Access to it could be limited.
