That wasn't the point I was trying to make. You discussed maximizing activity by going to RD and evening EMH. I was pointing out that that isn't an option for many people. For us, FP- was our way of being able to maximize our time in the parks, as we pretty much have to be in the parks during the midday time when crowds are highest (since late isn't an option, and early is iffy).
No matter what way you slice it, 3 FP+s is less than the 5-7 we were able to get in MK previously. Thus, we will be waiting in more lines than we have in the past, and therefore not maximizing our time as much as we had previously.
In fact, using FP+ could even cause us to spend more time apart as a family - something I did e-mail Disney about. If DH and I are there alone, we basically have to choose to either FP+ the rides DD can ride that need it (think PP, ETWB, etc) or FPing the rides we want to ride (the mountains). If we FP her rides to minimize the chances of toddler meltdowns, that means standing in potentially long SB lines for the mtns (esp. during spring break season, when we were there last year)..which means our family being apart (1 parent in line, one w/her) while waiting. With the 60min+ SB times over spring break, that's not an option that thrills me. OTOH, if we FP our rides, then we have a toddler in a long line (as PP, ETWB can be just as long as the mtns in busy seasons) upping the meltdown possibilities.
These are not choices we had to make when we could get more than 3 FPs in a day. DH and I could enjoy our rides, we could get FPs for DDs as well, and everyone was well rested and happy.
