Assuming MK and a mid-high crowd level, what's your strategy on when to plan your 3 fp's? If you plan to arrive at RD, what time do you want your first FP to start? Do you use them early and try to get more or save them for the most crowded time?
Before our first trip to Disney as a family, I read some guide books that suggested two things I've always used in my planning process:
1.) "The hotel swimming pool," was the response of children to the question of favorite part of their Disney vacation.
2.) Most children have a four-hour window of time to give to a Park before wanting a serious alternative.
We Rope Drop (9am) most days with an expectation of leaving by 2pm - after a small'ish lunch and possibly our last FP+.
To accomplish this goal, we often get FP+ for 9:15, 10:15, 11:15am - with lunch plan before noon to be completed sometime around 1pm. Also gives us time for another attraction, to stroll into shops on bad-weather days (utilizing those coupons we received from Qwik Service that morning), or scurry back to the pool on warmer days. Parades, dinner plans and/or nighttime (Park hopping) activities can also impact this block of time that might also include travel to/from a resort. We don't rush out of a Park, we decide if leaving offers a better alternative after having accomplished our 'must-do's' for the day.
We start at E-ticket rides after Rope Drop and utilize that 9:15FP closer to 10:15. That's a little over an hour of low crowds and 3-6 rides in any Park. Then, get on standby until that 10:15FP starts to expire at 11:15 (at least 2 more rides). Sometimes our 3rd FP will be before lunch, sometimes afterwards. By and large, we do not do roller coaster rides immediately after eating. Magic Kingdom is the only Park that has enough rides that we ever feel as if we could have stayed much longer and sometimes we do. We can take a 4th FP+ to just about anything at that point if we think it possible we are remaining in the Park or we can just pop into Country Bears or Monsters Laugh in the typical 10 minute wait period.
We utilize a similar strategy for evening FP+ selections. We start with our ADR's (because those are 180-day advance for all of us) and work backward from how late can our child stay out before that 4-hour window becomes meaningful.
Don't get me wrong, on some days, we are certainly capable of 6- or more hours in a Park, but we plan around those days with that 'Hotel Swimming Pool," and 4-hour window in mind. We no longer find ourselves dragging along at any point of our vacation. We try to front-load the vacation with long days so that we can double-back to anything we missed the second-half of our vacation. We leave more relaxed (sorry, some of us leave Disney relaxed).
FP+ has allowed my family the ability to enjoy as many rides as we need in a day and also enjoy our vacation to the fullest.....but it does take some planning.
