We are on the June 2 Northbound on Nieuw Amsterdam arriving in Whittier on June 9. We have an 8PM flight out of anchorage and we would like to get a flightseeing tour to Lake Clark National Park if possible. The available services in Anchorage state we need to be there by 8AM. My question: Is it possible to get to Anchorage by 8AM if the posted disembarkation time is 7AM? Thanks for the help.
