You want a premium solo experience, and you are willing to pay for it. However, you don’t have an unlimited budget. Fortunately, there is a cruise line for you. You aren’t rich, or you just still care about the value you receive for your money. So, you don’t want the mass-market option, even though NCL is cheaper for solo travelers.
Your Cruise Line is:
Princess
Princess is a premium cruise line, at a modest price. So modest, in fact, that some itineraries are cheaper than the mass-market rate. A good example of that is Alaska, where Princess is the biggest player.
