The Emerald Princess is fairly big, 3k passengers, and subsequently the embarkation was cumbersome. I recommend boarding later rather than earlier.
We were well forward on the aloha deck and found our room comfy with lots of space for clothes., the usual wet tissue test over mirrors and hung pictures indicated neglect. I know that 4 hour turn around is tight. Still....
Ship is well laid out, good music and lots of floor space for dancing. I complement the band in the Explore lounge, they actually knew strict tempo ballroom. Bonus for those of us who love the dance floor.
