I have two young kids, so we will be doing some dividing up during our trip. My question is- if I have my 3rd FP of the day scheduled (say for HM) for just myself. Once my husband and son use their 3rd one (say for Splash), will I be able to copy my existing HM to them for their 4th? If so, can this be done on the app? Or do all 4th+ FP dealings need to go through the kiosk? Hope that makes sense.
