Hit my "60 day" mark this morning.
For me, FPP's did not open at 7:00:00am or 7:00:02am so I hit refresh and was on making FPP's at 7:00:05am.
Both Pandora rides where an easy get even for the first day of my visit. In fact I went back in around noon to tweek things and there was still wide availability for both Pandora attractions.
7DMT already had an earliest time of 3:30pm, I did not try for a Frozen.
Don't forget if you are booking shows (ie Lion King or Rivers of light) they block you early. For example, a 3:00pm Lion King show will block you from making another FPP between 2:30pm & 3:30pm.
If you are after 7DMT or Frozen Ever After, you might consider going for those first and then Pandora.
Don't forget you can now make a single FPP on a given day, move to another day, and then come back to finish up the first day later.
