We are on a B2B on Utopia right now, actually, and even with it being Valentine’s Day/long weekend, there has been a really nice group of passengers for both sailings. There are TONS of kids, more than any other cruise the ship has completed in its short lifespan, so much so that the bar staff has been complaining about how dead the bar venues have been. Other than mind-numbingly loud music from the pool deck for sailaway, I haven’t noticed a party vibe any more than on our Wish sailings.
