We go for a week, and although we don't take a day off in the middle, we do take the middle of each day (3-4 hours) and take a nap/swim break away from the parks, which I think helps.
I get it, though, OP. The strollers are annoying, no doubt, and I find myself cursing them by the end of the week, too. "Stroller abuse" is rampant -- by which I
do not mean people with tired toddlers or babies who legitimately need a stroller (so please, parents of little ones or kids who have a physical disability that necessitates a stroller, please don't think I'm talking about you -- I was once in your shoes). I'm talking about the people who shove around ginormous strollers as if they are battering rams designed to cut through crowds, without concern for the physical safety of others around them (my 70-year-old father ended up with a deep, bleeding gash in the back of his ankle on our last visit, thanks to a careless stroller operator who didn't even bother to apologize after ramming him three separate times), and for no apparent purpose except to avoid having to carry their own ridiculously oversized park bags and purchases, or to coddle half-grown older children who are fully capable of walking. Ditto for tour groups, although we try to choose dates when they are less likely to be visiting, and steer clear of them when we encounter them.
Still, as annoying as these types can be, we find that by structuring our days to include rope drop arrivals, long afternoon breaks, and slightly later evenings, we avoid them as much as possible. Stroller abusers and tour groups tend to be cumbersome, slow-moving, and prone to late arrivals and early departures, and kids tend to be at their whiniest and melt-downiest in the middle of the afternoon when they're hot and tired, so confining your heavy-duty park touring time to the early morning and late afternoon/evening is a nice way to avoid many of them. At the end of the day, these folks are part of the Disney experience, like it or not, and the best thing to do is just grin and bear it, and focus on the larger picture. The only thing about it that we can control is our own attitude.
