Update on my experience:
1) in our party of 5, I booked 3 FP for space mountain and 2 to Ride Buzz. We went to space mountain together and got a child swap added to my band and the two older kids band.
2) i rode buzz with my younger daughter while they rode space, and then i rode space with child swap. My husband and daughter rode people mover.
We did something similar on expedition Everest- only booking fast passes for 3 people.
Also as a reminder, my daughter is not too short to ride, she just doesn’t care for those rides.
ALSO: there is a window of time to use the child swap - basically within an hour and a half or so, depending on the line group one is waiting in. But you DO need to use it pretty much back to back - you can’t save it like before.
Here’s my previous post:
We used it several times.
Our whole group had fast pass (even my non-rider)
Group #1 was my husband, my sister, my son and nephew. All with their fast passes. (I waited with my daughter)
Group #2 was me with my son and nephew riding again (using the rider swap entitlement that’s had been added to their band).
We are going again on Saturday. This time, I booked a different fast pass for my daughter and myself while everyone else rides space mountain with fast pass.
I’m still going to try to get rider swap so I can ride space mountain - but not sure what will happen since I won’t have a space mountain FP. I’ll report back.
Edited to add: my daughter is tall enough for the rides we used digital rider swap on - she’s just too scared to ride (Big Thunder, splash, expedition Everest...)
