Normal
Two weeks ago I was on the Norwegian Wind, and a coworker from my office was on the RCI Voyager of the Seas, a much larger and newer ship. We had a very similar itinerary, including being docked in Cozumel the same day. The night before Cozumel, and the cruise back from Fort Lauderdale were very rough on the Wind. While I didn't get sea sick, it did take me about a week to get my land legs back. My coworker who had been on the Voyager said that their ship did not rock at all.
