I get there real early, well before the boarding has started, & I’m usually in the 1st group let into the terminal, & since I’m elite, in the 1st group to board. Perhaps I’ve been lucky but I’ve never been in a long line to get into the terminal or onto the ship.
Lunch in the MDR is nice to relax with a nice drink, & meeting new people.
Just my experiences but I been outside on deck later, & sometimes seen very long lines, so I felt great by arriving early.
