Can DD use her sisters MB to use FPP?

It’s going to be me, DH, DD’s 7 & 10. DD7 does not like roller coasters. Can we schedule 4 FPP and then DH and DD10 ride once and then myself and DD could ride again using her sisters MB?

We had no problems doing that last month.

In park, yes. To enter the park, no.

Don’t forget about rider swap passes. They apply to people who don’t want to ride and not just short people. That way you and the timid child could use the fast pass on something more enjoyable while you and the older child could still ride
