We'll be at WDW this January, but I'm asking in particular about January 20-21.
What are the chances of getting "day of" add-on FPs for headliners at DHS and EPCOT? Specifically wondering about Soarin' and Tower of Terror, and we'd obviously not even have an opportunity to try for them until midday, on account of having other set plans earlier in the day.
Is there a chart anywhere that sort of identifies how far out you need to book at FP+ for any given attraction? For example, I know from experience that Anna and Elsa basically requires you to be online at midnight at the 60 day mark, whereas COP I would assume you could get the day of without any problem most days.
