I am an equal opportunity cruiser, preferring to mix it up when selecting cruises. Many prefer to sail only one line, building up their level of loyalty.
Is there a line, you just said..I don't want to sail them, or if you sailed them, you said never again?
Do you feel the perks you get, are worth your loyalty, and to those who only sail one line, do you think perhaps you might be looking through rose colored glasses at times? and If you had just a so so cruise, would it be tough to admit you were not thrilled, and consider another line?
For me I would only sail HAL, if it were a CM cruise.I would not sail it, as a couple. We sailed 2 ships, and, unless it was a hosted cruise, I would pass..
