Paper fastpass worked beautifully on this setup & we used this many a time. With everything being digital now, even if you don’t purchase MaxPass and just use the FastPass, it varies widely on how they manage the rider switch if not everyone has a FP. Rather than issue a paper rider switch for any 3 people they now, ask for the 3 passes to load the rider switch on & will give them a 1 hour window. They give you at least 15-20 min. before that window will start to allow the first group riding enough time to get on & complete the ride. However, sometimes instead of that 15-20 min. gap to start the window, they will program that gap to equal that of the standby wait. It really varies from day to day, CM to CM, but in my experience, if you have FPs for everyone, they will give you just the 15-20 min window. If you don’t, then they will add the length of the standby queue before the rider switch 1 hr window opens.
We were there the day that rider switches got switched to digital (it happened a couple of months after FastPasses were made digital due to glitches in the system) & it was a mess that first week with CMs not ever having been trained to do it & unknowingly being expected one day how to navigate this relatively new system to program on a rider switch. It has come a long way, but I have still heard of inconsistencies on how & when the rider switch is being issued.
That being said, after a few very difficult & trying attempts (for both me & the CMs) I abandoned using that tip with the new digital FastPass & just get FPs for all of us together. It is how the system is designed to be used, & while it was a nice loophole of the paper system (because you didn’t really NEED 4 papers when only 3 people were going through the line & 1 was staying back with a non-rider), they’ve now closed the loophole with the digital conversion. Not to mention the extremely shortened window to use the swap, but that’s a whole other story!
