We always remained in our window for FP return times and never really found the need to pull a ton of FPs. An example of our old touring plans at each park would be:
HS- arrive at rope drop, dad (who doesn't do thrill rides) goes and gets TSM FPs, everyone else goes to standby RnR and ToT, by the time we're done TSM FP is good, take the long way to TSM and grab a Star Tours FP, ride TSM, watch the Muppets, ST FP is good, ride ST, standby Beauty and the Beast, lunch, standby Indy, standby LMA, catch Little Mermaid or GMR as a filler before standy Fantasmic! (FP total: 2 minimum, more if we wanted to re-ride RnR/ToT.)
EPCOT- arrive at rope drop, I (the fittest) trot to get Soarin' FPs, meet family by the Seas, standby Nemo, hang out in the aquarium, return to the Land, ride the greenhouse boat, FP for Soarin' is good, ride Soarin', walk to Test Track, grab a TT FP, standby Ellen and Mission Space, TT FP is good, ride TT, standby Spaceship Earth, head to WS, lunch, standby everything in WS. (FP total: 2 minimum, more if we wanted to re-ride TT/Soarin'.)
MK- arrive at rope drop, I trot to Fantasyland and grab FPs for Peter Pan, standby Small World to Pooh to carousel to Philharmagic, FP for PP is good, ride PP, grab FP for HM, standby BTMRR-PotC-Jungle Cruise-Tiki Room, FP for HM is good, grab FP for Splash Mountain, ride HM, lunch, standby BLSRS and Laugh Floor, grab FP for Space Mountain, go ride Splash, shop on Main Street, dinner, go ride Space, head to TotW for Wishes!. (FP total: 4.)
AK: arrive at rope drop, Dad (doesn't do rollercoasters) gets FPs for the safari while mom and I standby EE, standby Kali, FPs for safari are good, ride safari, watch FoW, lunch, catch FotLK, grab FPs for Dinosaur, catch Nemo (LOL), standby PW, FPs for Dinosaur are good, ride Dinosaur, leave for dinner elsewhere. (FP total: 2).
This is why I'm not entirely convinced our touring plans will be changed by FP+, but I do expect longer standby lines since people will no longer be able to do as a PP said and pull a large handful of FPs and come back at their leisure rather than in their window.
