Cheapest 15 day Cruise on Norwegian is $649. Just line those up back to back. They even have an offer for 70% off for your second guest, which makes it ~$900 for 2 people.
That doesn't include all the fees, primarily "gratuities". Also, I think prices are pretty good right now. It also varies with the time of the year. I would expect prices to go up as the industry recovers from the pandemic. Of course, frequent cruisers get added upgrades and special offers from the cruise lines, too.
