When we visit Universal, mostly we just wander the parks going wherever we feel like going in the moment, we especially do this when we have Express Pass. There's just no reason to plan rides.
What's even better is that we feel 100% free to do re-rides.
Hagrid's is a bit like FoP. The throng heads to that queue first thing in the morning, and then they stay in that queue for an hour or longer. Meanwhile, if you are there early, the rest of the rides all have short waits. IF you follow the herd though, then by the time you get off FoP/Hagrid's, well, you just keep following the herd all day.
It might be partly semantics, but we don't plan. We do however, employ a bit of strategy when touring any park. Generally, if we arrive early then we start the day with a headliner-ish ride, and try to cover a few before the crowd hits. Mid-day,we tend to do lesser wait attractions, or anything that has a pop-up short wait. Like if a ride happens to re-open as we are walking by it.
We don't see a lot of shows. If you like shows, then yeah, those require a bit of a 'plan.' For us, that's usually,"Oh hey, we have an hour to kill, and the bird show starts in 5 min, let's go see it."
Mind, there is a small exception for something that is very new. If you're visiting the day anew ride opens, then you gotta deal with being in the throng. Hagrid's was that way when it opened, but that is no longer the best approach.
I should add, we are often willing to gamble.
