We have not been to WDW for 3 years, and so much has changed with ADRs. We have park hoppers, and reservations at PO. Can we only make ADRs for the park in which we have a park reservation? Specifically, can we make an ADR for dinner at park that we plan to hop to? And, can we make ADRs for our entire vacation on the first day of our 60 day window?
