No it wasn't. It was impossible. Did you ever TRY to get a FP+ to ride the 7 Dwarfs, Flight of Passage, or to meet Anna and Elsa back in 2014-2016 during peak Frozen mania? You couldn't get those FP+ at all. Sure maybe they were available the first 5 minutes after your 60 day window opened up, but if you tried 11 minutes after your window opened up they were gone. I don't even know what the thumbnail for the Anna Elsa meet and greet looked like because I never saw it! And if you stayed offsite, my god you couldn't even get splash mountain for a decent time that worked for you.
So, sure, if you were an OCD uber planner who counted down the seconds when your window opened I'm sure FP+ was great. But if you had a life and forgot precisely the second your 60-day window opened up then FP+ was pretty poor. Or maybe you went on Wednesdays in September and never had a problem. But if you are normal and have kids who go to school then FP+ did NOT work. It, frankly, sucked. You'd end up with Haunted Mansion, Pirates, and Thunder Mountain. And Pirates/HM didn't even HAVE paper FP because they never had long waits. So what did FP+ do for regular people? Make things much worse.
