I’ve been on 6 cruises, I think. You’d have to work at it to get over most of the rails. The lowest I’ve seen is a meter high. Perhaps when they haul these folks out of the ocean they should report their BAL.
I don’t enjoy the majority of the cruise “activities,” other than live music. My pleasures on a cruise are to get up before dawn and watch the sun rise, get to port and do or see something interesting, eat some local food and have some conversations, shop a little, and return to the ship. I usually lose weight on a cruise because I walk around a lot on the decks, fruit and vegetables are almost always available for extended hours, and I don’t over-order at meals.
My last cruise, on Costa, an Italian line:
Savona, Italy: Embark after train trip from Firenze
Napoli, Italy: Organized tour to Pompeii
Palermo, Sicily: Walking around the open air market; looking at architecture, eating gelato
Tunis, Tunisia: Organized tour to Carthage and the Bardo Museum (excellent, by the way)
Palma de Mallorca: Walking along the waterfront; shopping; dinner on the water
Barcelona, Spain: City tour bus to Gaudi’s Sacrada Familia; walking La Rambla; lunch; long walk around the waterfront
Marseilles, France: Disembark (we could have continued to Savona); train to Arles for the night
Cruises get me places I might not otherwise have time or resources to see, and they provide safety for women travelers. Cruises have gotten us to the Parthenon; the Pyramids at Giza and Egyptian Museum; the Western Wall, the Dome of the Rock, and the Church of the Holy Sepulcher; Ephesus; Tulum; the lava fields of Hawaii; Glacier Bay; hiking on a glacier; snorkling in Kauai. Not to mention all of the towns and cities we’ve visited. These cruises have served as the basis for learning about the world, and to inform us about where we would or wouldn’t like to visit in more depth.
I can’t defend their environmental record, which isn’t good; I can say that information about which lines do a better job of it is readily available, and that reusing one’s towels and sheets, and not heaping up one’s plate and discarding most of the food, are all ways that individual travelers can decrease their contribution to pollution.
