Hey @Eaglecw if you show up at the pier at 11:30, they will let you check in so long as they've cleared disembarking passengers (which they should have by that time). The question will be if they will make you wait until your group or let you get on. So, regardless, you will be allowed in the terminal.
Our flight was early, so early the transfer shuttles were not running yet. We were on the 1st one, waited outside the terminal while returning passengers finished disembarking, checked in, waited just a bit until they started calling for people to board, and went on. We had dropped our bags at our cabin (which was not yet ready), finished Mariners lunch and were enjoying wine on our balcony before our scheduled boarding time π€
My boarding pass showed 1:20, group B but my husband's didn't show one at all. We received no pushback when we joined the line after the Mariners.
This was Seattle April 29.
Welcome to HAL - enjoy your cruise!
Please update as to the outcome - I'm sure many of us are curious to know what happened.
