I have to join here as I had a similar experience, going April 12-15 and had planned to go solo. So I got up at 7am on Sunday, made all my fastpasses, got FoP for day 3. Then later that day, my dad said he’d join me, didn’t have tickets, had to buy them, but luckily still got FoP at a time maybe 1.5 hours after my previous time. Then, I decided to switch AK to day 1 (crazy!), canceled my Epcot fastpasses for that day, but still got FoP at 5:30, kept checking and found one for 2:30 that day and it was perfect!
TLDR: FoP was available less than 60 days out!
