Splash Mountain and Child Swap

For some reason on my touring plans, when I add Child Swap to Splash Mountain, the “Duration” sky rockets to 41 minutes. Any idea why? Is that accurate?

It includes the time it takes to swap and wait in fpp queue and do the second ride.

I assumed that was the case, just a bit shocked that it would take 41 minutes to ride it twice. I guess the ride is longer than I remember.

The actual ride is 12 minutes long not including getting in and out the boat etc.
