Both ships are north of Tracy Arm, Eurodam is in the lead. Discovery Pr should not beat Eurodam in unless she speeds up - a lot. She could pass Kdam though.
I have no idea what they are doing with the pier assignments this year. There seems to be no consistency, except that the first large cruise ship in gets FKL. Last year at the end of the year - they had to adjust - because of pier availability at other ports being affected by natural events. [Rock slides, dock repairs IIRC.}
