If you remember the paper fastpass days, selecting a G+ is no different. Back then you had to cross the park to pull a paper fastpass and then cross the park for your return time. I was more of a
Disneyland vet back then, but rides like Radiator Springs Racers had 20 minute waits just to pull a paper fastpass. Maxpass and now G+ now allow you to book on your phone without going to the attraction first. This is a big advantage over paper fastpasses. Plus you can refresh for better times. The “strategy” that you need to “study” is no different than the paper fastpass era. This is how it worked for almost 20 years in Disneyland and how it worked in WDW until FP+.
While I agree that FP+ was ideal for uber planners since they could select the times of day for their first three attractions in advance and can plan their time in the park to the minute, and it gave a huge advantage to resort guests to book at 60 days, Disney has come right out and said that one of the reasons for G+ is that some (not sure if most, all, or very little), didn’t want to plan every second of their time and want to be flexible with their plans. G+ certainly puts planners and last minute guests on the same playing field day-of. And I think that was one of Disney’s intentions. But I also think they got an earful from the planners, which is why they announced recently that starting in 2024, guests will be able to pre-book certain G+ selections in advance (we’ll have to see).
Some people think a relaxing vacation is showing up at the park and going with the flow a-la G+, while others thinks a relaxing vacation needs to be planned. Everyone is different.
