We will be staying at PO Riverside for 5 nights and 6 days at WDW. We will be purchasing single park tickets for 4 of the days. On the other two days, a Castmember will be signing us into one of the parks. When I hit the 60 day window for Fastpass+ selections, can I make selections for all of my resort stay days? Will I be limited to making choices for only as many days as I have purchased tickets?
