Time will tell whether these limits will smooth things out a bit. But when I was at WDW a few weeks ago, the standby lines were all pretty light (15-20 minutes) except for Soarin, Peter Pan and Toy Story Midway Mania (all of which we FastPassed).
What I don't understand is why in the world is there always such an obnoxious line for Peter Pan? I absolutely love the ride but the line always seems excessive for that one in particular. Winnie the Pooh is also one that surprisingly has shockingly long lines.
Sorry, DisneyJedi but the traditional system has failed many rides like Peter Pan, Winnie the Pooh, and Toy Story Midway Mania. Toy Story Midway Mania is an interesting one. If you don't get to Hollywood Studios right when it opens, not only is the standby entrance wait excessive but the fastpass line (to receive the fastpass for later on in the day) is just as long and the daily amount of fastpasses available for the ride is distributed within a half hour of the park opening. Something is VERY wrong there. The new way prevents that so while not a perfect system, that's a plus 1 for Fastpass+ and a minus 10 for the Traditional Fastpass System.
It was a slow day, and we waited probably 70-80 minutes for Splash Mountain because they kept closing the line to let all the FastPassers through.
That was the thing I noticed when waiting in the standby line for Peter Pan's Flight, and got really annoyed, as there seemed to be a neverending line of people coming in the Fastpass line. I thought, why can't they alternate between the 2 lines. It's also what annoys me about the single rider line, as that plays 3rd fiddle to the standby and Fastpass lines.
See, I think the single rider line is the most ingenious idea they came up with for lines. I was able to go on a ride by myself (usually I want to do a ride no one else in my party wants to), not wait in an obnoxious line when it's just me going on so I don't hold my party back, and my appearance in the line didn't hinder the standby wait. They merged me in right along with them. There's usually very few single riders getting on at a given time. Most people go on with parties. The real line stoppers for standby wait is the fastpass line as I've seen them let in 30+ people at one time in the fastpass entrance.
