I think we're only planning to park hop on one or two days. Actually, Epcot is the place I'm most tempted to pick just a tier 1 fp (FEA any day I can get it) and then leave the other slots open for additional fastpasses at other parks. I just feel like there aren't any other rides in Epcot that really need a fastpass other than the tier 1's. We don't do the character spot (though I hope to catch Joy & Sadness at rope drop, but that's not who the "character spot" fastpass is for anyway, as I'm sure you know) and we only need one ride on Spaceship:Earth. Other than those, I think about everything else can be done at various times throughout the day with very short waits. Mission:Space is probably another than could possibly need a fp, but again, one time on that ride for the 2-3 people in my party who will ride it is enough.
