Our plans for marathon weekend changed and instead of all 3 of us flying down and arriving together, my mom and sister will be driving sis's car down because she checks in for the CP on January 9th. The BRP ressie was made by me but I'll be the last to arrive. Can they check in earlier at POR? They are both PAP holders also so presenting an AP isn't a problem, it just wouldn't be the one the ressie was made under. TIA
