One problem on Royal class ships is that many venues like pizzeria, sushi bar and Crooners are all surrounding the piazza and the noise just goes straight up into the venues
All Royal class ships have so many venues around the piazza it is almost impossible to get away from the noise. A little better on Grand class but some band and hosts just seem to scream
It depends on port and customs. When we sail from Vancouver to Seattle or Vancouver to Whittier on a first leg you go through US customs when you board so no need to leave ship at all
Just call the dine line when you get on board and change dates and times. I have never had a problem getting into Sabatini’s for Crown Grille you may have less choices Not every table is available on the app
