And exactly what I was referring to when I used the word savvy. There were more tricks to be used than that though. I was out of the loop on some of them, but it wasn' hard- IF you knew the tricks and were willing to use them.
With FP+, the field has leveled out- other than an extra 30 days to book for on site guests- which I used to think was huge and have since discovered it's not all that much of an advantage- there are no little hidden tricks or gimmicks. And I suspect it's the source of great frustration to many people- understandably so.
2 things, respectfully:
(1) I never used the "tricks" as you referred to them. I pulled a paper fastpass and returned within the time window. It worked great under those circumstances, for me, and probably others. As far as I know, there were only two "tricks" (in quotes because I don't think that's an accurate characterization, but I'll play along): using them after the end of the stated return time (which was shut down before the advent of FP+), and there were *some* instances where you could pull FPs for two different attractions even though the first time window had not expired.
(2) OF COURSE there are "tricks" (again, don't agree with the word, but for argument's sake ...) for the new system! And it's not been around long enough for all of them to be fully exploited. Your least favorite, I think, is the old magic bands under a different
MDE for extra same day FPs. I know you're also not a fan of throwaway rooms. You can also use swapping MBs to your advantage (ask me how if you want to know more - I have 4 FPs for our MK days for the "riders" in my family

). Another thing that has been discussed, but I haven't seen confirmation of lately, is that you can potentially make 3 advance FPs in Epcot (for instance), cancel 2 (anything but Soarin or Test Track), and then immediately book your 4th FP after you ride Test Track or Soarin. I'm sure there are more.
No offense (truly), but it's ironic to me that you state there are no "tricks" with FP+, but you have actually been a very vocal opponent of some of those "tricks", or as I like to call them, "strategies".
I think there are pros and cons for legacy FP and for FP+. I don't think either is perfect or irreparably flawed. But I wholeheartedly disagree with the idea that the playing field has now been levelled. I think it's more lopsided than before, personally.
I also whole heartedly disagree that being "savvy" (I would use the word "knowledgeable") no longer yields an advantage. I'm using several of the strategies I mentioned above, and I absolutely feel I have an advantage over (at least some of) those who don't use them.
