Switching Parties with CL VIP FPP?

For those of you who have done the club-level VIP FPP program, were you able to switch parties on a ride with a club level FPP? I’ve heard that the CL FPP requires a call to Disney Signature Services to modify; that you cannot modify them on MDE. Did anyone try to do switch parties by calling DSS? I’m wondering if I will be able to transfer any of my kids’ club level FPP to me on a given day if they are not going to use them.

Will they have scanned into the park? Can you just use their MBs?

Hi Tink–no, they will not have scanned into the park.
