“One that doesn't last more than a week I think, and maybe somewhere like the Arctic just because I don't know how else I'd ever get there. The Caribbean would be cool though.”

“I would go on one of those targeting my age demographic (millennial), possibly for a tour around the Mediterranean.”

“I like sunshine, hot weather and tropical surroundings, so it would be definitely a "summer cruise" to hot places - maybe also to some deserted islands.”

“Probably a river cruise - I like the idea of having plenty to see on either side of me as I go along, rather than just open water.”

“Probably to the extremes, either something that emphasises staying on board a lot and a real luxury experience or one that emphasises getting out and seeing the countries you're travelling past a lot. Probably somewhere sunny like the Caribbean or somewhere interesting like the Norwegian fjords.”

“A cruise that maximises freedom to explore destinations, and caters to people around my age without being a booze cruise. Scandinavia or the Mediterranean would be good for making lots of excursions, but I also think a cruise would be a great (and expensive) way to experience the Caribbean.”

“I'd probably go on a music festival type cruise, like the Salty Dog cruise which runs round the Caribbean.”

“[An] Amazon cruise to see the beauty, and Peru would be a great place to visit.”

“Absolutely, I'd like to know what's being done to prevent harmful emissions and how waste is handled.”

“Yes. The cruise industry is famous for its poor efforts in becoming more sustainable so an operator's positive environmental record would definitely be a plus for me.”

“If I could choose an eco-friendly cruise for a trip when I'm looking, [even if] it would be [more] expensive, I would definitely pick the better [one] for our planet.”

“Yes - minimising harmful emissions into the sea would be an important factor, as well as air quality for passengers onboard the ship. I wouldn't want to contribute to a cruise industry that has a major negative impact on the local environment at destinations.”

“Yes, although it would be secondary to other factors such as route, because if I was really worried about the environment I wouldn't go on a cruise at all.”

“I like to think I'd at least bear it in mind but cost would probably be the dominant factor. I'd look over it if only because of a slightly heightened awareness of how bad cruise ships generally have been for the environment.”

“Probably not. I would be more concerned about safety of the boat, given that recently some have begun to capsize in the recent past.”

“No, it's not something I've ever thought about, but I will now!”

“Ensure time on the ship is kept to a minimum and make it more about the destination.”

“They could offer more budget options in exciting locations with lots to do - a lot of operators seem to focus on making their ships more swanky, but I'd be much more interested in what's happening onshore than onboard.”

“Realign imagery to seem more appealing to younger consumers, [and] make the argument for why it's a well-priced way to travel.”

“A relatively short and less expensive option - maybe a river cruise - would be a good way to try out the format, and if I enjoyed that I'd consider booking something larger.”

“Lower their prices, run off of cleanly sourced power, and have some desirable entertainment.”

“Offer small, environmentally friendly, eco-conscious trips with a limited number of passengers and a strong focus on nature.”

“Prices tend to be too high, and [there’s a] perception of [cruise ships] being full of old people. Maybe put an age cap on some cruises.”

“Offer lots of freedom and opportunities to explore. I would also want a big cruise ship with lots of things to do. Also, amazing food.”
