I'm really not sure exactly what you're asking, but here's a brief explanation of how it works...
- Family approaches the CM at the ride entrance and asks for a Rider Switch pass.
- One adult waits with the too short child/baby while everyone else in the group rides (either via the regular standby line or fast pass if you have them)
- After they are done, the waiting adult and up to two others can ride using the Rider Switch Pass via the FP entrance (Ticket is good for up to 3 people total)
Notes:
- The waiting adult and child do not have to stay near the ride. You can use this time to get a snack, do another attraction, etc.
- You do not have to ride immediately after the first part of your group. The RS pass is good for the rest of the day, so you can return later to use it if that is more convenient for you.

So, if 2 people ride, and one waits, one of the people who rides can go on the ride again with the person who waited?
Why did they not have this at Six Flags when I was a teenager?![]()
As long as you are waiting with a child who can not ride due to a height restriction = yes.
Can you combine fast passes with rider swap? And can 2 people sit out, for example could my husband and I ride while my ILs sat with the kids and then the 2 of them ride? Thanks!
Yes, on both counts! We used to get, for example, 2 FP for Splash Mtn and 2 for Thunder Mtn (with 4 tickets, total). Then, we'd get a RSP, 2 of us would ride with the FP and later the other parent and the older child would ride using the RSP. Repeat at other attraction. It helped cut down on the down-time the too-short child had to endure.
As long as you present the too-short child to the CM, you can split up any way you want to. When traveling in a big group (we once did Disney with a group of 14, 2 of whom were under-height), we would split up so that several of us waited with the youngest kids and then traded off, which allowed the parents of the kids to actually get to experience attractions together - a rarity when you have an under-height child!
IME using FP with RS can be hit or miss- some some CM's will insist that every member of the party (except the non rider) have a FP and then they will trade the RSP for the FP of the person staying behind with the non rider.
Last time we went to WDW, we either didn't have a good understanding of rider swap, or we ran into cast members who didn't fully understand it. So let me give a scenario to see if I get it now.
Our next trip will be me, dh, a 42" kid, and a 36" kid. Here's a scenario. We get 2 Fastpasses for Soarin' with my ticket and dh's ticket. We simultaneously get 2 Fastpasses for Test Track with the girls' tickets. Fastpass return time for both rides is 10-10:30. At 10, we go to Soarin'. Go to the regular line cast member and say we want a rider swap. They see that YDD is too short, so they give us the rider swap pass. We go get the stroller situated. Dh and ODD use the 2 Fastpasses to ride Soarin' while I wait with YDD.
When they're done, we head over to Test Track. Again, we approach the cast member at the regular line and say we want a rider swap. They give us the pass, we get the stroller situated. I ride Test Track with ODD, using the 2 Fastpasses. When we're done, we now have a rider swap pass for both Soarin' and Test Track. We can use them at any time during the day. And since each rider swap is good for up to 3 people, ODD could ride each of them a second time.
Is that right?
Can you use the rider swap if the child meets the height requirements but just doesn't want to go on the ride?
