I just posted elsewhere. our trip as that FP was kind of neutral.
Yes, there was a limit of three fp, but the trade off is less time spent collecting fp. So of us, it kind of balanced out.
It was also perhaps not completely fair, because this time we went during a moderately busy time (MLK Jr weekend) and our prior trip was during a rather slow time. The parks were definitely more crowded this trip compared to our last two trips.
As far as I'm concerned, previously, there were only two *real* FP attractions in Epcot (TT, Soarin'), AK (safari, EE, maybe Kali on a hot day), and HS (TSM, RnRC, maybe Star Tours/ToT on very busy days only). Sometimes in the past, we used more than three FP for rerides.
So mainly we only felt the difference in MK. All in all it ended up a trade off for us. Instead of having to gather fp's, we spent a little more time in stand by queues, but I think collectively it was still a time savings to use fp+. Obtaining old style fp was quite time consuming. (and we are quick walkers)I think many naysayers are underrepresenting that factor.
One factor perhaps is that most of the time, the new FP+ queues were quicker than they used to be under old FP. Most of the time, they got us on the ride in under ten minutes. Many attractions that used to take ten with old FP were faster.
I will say...I'm comparing new fp to the way FP to ENFORCED old FP of the last year....for us...well... I liked it when we could use FP past the time window. We usually used them in the time window; it was just relaxing to know that if you did show up late it was okay. Mostly, when we did use our fp late- it was usually VERY late at night, so late night that the queues were down to almost nothing. Still, it was relaxing to have that promise.
I think that's a very good review. You related FP+ to your previous use of FP and how it affected you. Very cool and everyone knows exactly what you are talking about and describing.
Good point on the time it took to collect paper fastpasses. For my family it was never a big deal as I was the 'runner'. If we were due for a FP, I'd hustle to where I needed to pull them and then meet up with my family.
Pretty much unless I needed to go from SM to BTMRR (which I wouldn't do anyway) it was never a big deal and I could get off a ride and hoof it to virtually anywhere in the park and be at the next destination to rejoin my family in under ten minutes.
I never cared about "running" (speed walking) for them and my family had a chance to saunter on to the next stop. Worked out very well.
I agree 100% with AK and EP and FP+ being fine for those parks. DHS isn't bad, except if you can't make your TSM time you won't be able to change it to a later time in the day unless it's a Tuesday with a crowd rating of 1, perhaps Wednesday crowd ratings of 1 as well

MK is the nightmare IMO. Considering we pretty much only travel off season now, it's not going to be the end of the world but it still is a huge detriment to the way we do things at MK.
That's setting aside the huge issues with
MDE during peak hours in the park. I would hope they spend the money to upgrade the wifi and severs themselves, on peak times, even with 4G, the MDE lagged for me.
My friends who were there over MLK week with you had similar issues during peak hours and that weekend. Like my visit it was better in the days just before that weekend.
Also apparently off site guests will have to use kiosks and not the MDE for FP+? They had another couple who went with them for a few days and couldn't do MDE and were told they had to use kiosks. Don't have any more info than that on it.
The MB's or "Magic Trackers" as a cast member friend tells me they are called are nothing special to me.
Personally I'm not a fan of being tracked, real time, as I enter every single restaurant and shop (even if you don't buy anything) let alone them knowing exactly when I get on/off a ride and when I pass from one land into another.
That's just too dang creepy for my tastes. I didn't realize there was real time tracking in the bands as opposed to the passive RFID in the old room keys.
Next trip I may opt for passive key cards and not use the bands because of that. Again, it's too weird. A flat key card is waterproof anyway and my swim trunks have a zippered pocket. No worries there.
