Or even on the same ship. Every cruise is different. We hear from people who loved an Emerald cruise, so I don't think it's solely the fault of the ship. Emerald is the only grand class ship I have not sailed on, so I can't offer an opinion, but even with the Royal class ships, some have been more enjoyable than others. (I am missing just the Enchanted in that class.) Sun class? The FCC is finally gone this July, so I'll be over there on HAL and will miss the Sun and her sisters altogether.
