Since FEA seems to be a crowded mess right at Rope Drop, I would FP that one. Best strategy for one of the other two is to do it right at Rope Drop (or do it just before the park closes).
I would try to do the third one right at Rope Drop the second Epcot day, and I would probably get a FP that day for whichever one of the three rides I think we might want to ride a second time.
