I've been waiting for the day you can make additional fastpass reservations from your phone since the initial introduction of Fastpass+. It's one of the things I loved about the old system - the ability to have a fastpass for more than a few attractions if you planned your day right. Of course, the new system has greater benefits: the ability to schedule your day prior to entering the park, securing a morning fastpass instead of getting to the park at 9 only to have a fastpass for 8 that night, and my personal favorite, the ability to change your fastpass time at any point in the day, actually making everything more flexible than I thought it might be.
But what was missing was the ability to make additional fastpasses, which we now can, finally, do. I tend to have a rough idea of how my day is going to go, but I also love to plan on the spot, and from the second I realized I could have additional fastpasses, I went to town...or rather, all across Magic Kingdom...using and abusing the new system.
Since the park was open until midnight the night I was there, I spent most of the afternoon hours at The Grand Floridian for Afternoon Tea, which allowed me to get out of the heat and take a much needed break. But by the time I got back to Magic Kingdom, I was ready to go. Now, the way the system works is that if you use all three of your fastpasses earlier in the day, you can make additional fastpass selections at any point for any attraction in any park. Often times, you can snatch up a fastpass for only minutes out from the current time, which means you could be outside Pirates of the Caribbean and could probably get a fastpass to skip that half hour or 40 minute line right then and there, and the second you scan your magic band at the fastpass line entrance, you can make another fastpass selection from the app.
And you can keep doing this for as long as there are fastpasses available.
Once I figured all of this out, I just started making new fastpass selections while in line for the attraction I had the previous fastpass for. So I began at Pirates, and while in line I made a fastpass for another attraction, which I believe was for Big Thunder. While waiting for the fastpass, which started soon after, I took the train to Fantasyland and walked the rest of the way to Tomorrowland, where I got a phone case for a friend and headed on the PeopleMover. Then it was all the way back to Big Thunder, where I made a fastpass for the Barnstormer. While waiting for the Barnstormer I made a fastpass for Dumbo, and while waiting there I made one for Winnie the Pooh. As I waited for Winnie the Pooh I made a fastpass for the Tomorrowland Speedway, and from there I secured one for Buzz Lightyear, and then Peter Pan, and finally Splash Mountain. It brought me to a total of 12 fastpasses in one day, which I didn't think was humanly possible...but apparently is. I also had a chance to head on the Teacups, the Carrousel, Astro Orbiter and then Pirates one more time at the end, so I guess you could say that it was a wild five hours after my Afternoon Tea.
As for how many fastpasses you could get in one day, I'm sure 12 isn't the highest you could get, and I look forward to attempting to visit all the Magic Kingdom attractions in one day in the future, even if I have to really abuse the system to get there...but for now we'll say I'm utilizing the system, because really, that's what I'm doing! I'm just utilizing it to it's fullest potential...which may be a bit more than what Disney intended.
Next time, I estimate 16 or 17 fastpasses...but who knows how many are possible!
Have a magical day!
