Very much however Norway is still seen as a very good introduction to cruising. It has the Wow factor, new ship, no shuttle busses, no tenders, generally very polite nation and once you get on shore, you realise exactly how cheap it is to buy alcohol on board!
I see in the press yesterday, NCL being touted to order $4bn of new ships. I'll predict that JW will arrive and one of his first big things will be to lay a big order of new greener ships for delivery from 2026 onwards. Shipyards are heading quickly towards the end of their orderbooks. Get into early next year and the steel cutting will begin on the final ships on their books (deliveries late 2024/25). Now would be a good point to negotiate new-build ship prices.
As a company, you're correct that they weren't hitting break-even from cruise fare however with 17 smaller ships exiting the fleet, I believe that balance has now tipped.
Prices will go up. Some of the bargains which are out there are capacity fillers which are more prevalent at present whilst post-Covid confidence returns.
Re Princess, see my final comment below.
I do think that some of these will continue by I suspect it will be the Grand class ships (Ventura, Azura, maybe another once the two ships leave) which would undertake them. What is interesting is that since 2019, Ventura has done, or be scheduled to do, at least one 35 night Caribbean/US trip in early January. These cruises have been selling out therefore despite these being bigger ships there is still the interest.
Princess is currently cheap in the UK, but I do expect prices to rise. The UK has been very easy to add capacity too during the pandemic recovery. Additionally, the UK has been the testbed for the Princess plus package which has gone down very well.
