Indeed. One year, out of curiosity, I made spreadsheets of attraction wait times over long periods of time to figure out which attractions made the most sense ..... If wait times for a particular attraction was routinely awful, it made the most sense to target FPs for those attractions at the 60 day mark.
It turned out the spreadsheet didnt really matter, because the obvious attractions turned out to be the ones to target. In the MK, you really needed to stick with the mountains (especially splash, space and 7D) to get your 'money's worth'....for Epcot, TT, Soarin and the ride formerly known as Malestrom, etc. If you were settling for a fastpass on Nemo, you clearly slept in on the 60th day out.
