Which cruise line has the best nightlife?

honestly its a ship-by-ship thing more than just the line. we think msc or celebrity can be great, but the vibe on the older celebrity ships is way quieter than on the newer ones like the reflection. for a packed dance floor and actual energy, youre better off checking the specific ships itinerary and crowd - a shorter caribbean cruise on a royal oasis class ship is a different beast than a longer med sailing.
