Personally, I won’t book one that’s going to make me wait 90 minutes first thing in the morning. For instance, I see a lot of people suggest to book RSR first, which is good if you can get it early. But sometimes you come in at 8:15 and RSR is at 11:00, and booking it then isn’t necessary and will waste a lot of time when you could have knocked out many FP rides quickly. I’ll do some of the ones with quick returns and then grab RSR a couple of hours later (so maybe between 10-11 - after keeping an eye on return times, of course), and I usually end up with a mid-afternoon RSR return time.
Would booking that 11:00 RSR FP at 8:15 be “wrong”? Not really... but it’s not very efficient.
