Yeah, I didn't realize I wasn't using a height restricted ride in my example. They were just the first ones that popped into my head

Thanks for your reply!
So, then, it would be something more like....
Adult 1 - BTMRR, Splash, JC
Adult 2- SM, TLS, JC
Child - JC, POTC, HM
Adult 1 and Child go on BTMRR and Splash, then swap with Adult 2
Adult 2 and Child go on SM, TLS, then swap with Adult 1
All go on Jugle Cruise
Don't the other two FP's for POTC and HM go to waste?
So you are effectively turning 3 FP+ into 5?
Am I following this right?
Please keep in mind, the actual rides and logistics of getting from Tomorrowland to Liberty Square to Frontierland are irrelevant. I'm just trying to understand how it will work with FP+
