We've been cruising since 1976 and haven't been tempted to book Carnival yet. I believe we've been on all the other popularly priced lines plus a couple in the high end.
I'm sure it has its good points, but I can't believe it would be better for us than the lines we use now.
There is no necessary connection between the desire to lead and the ability to lead, and even less the ability to lead somewhere that will be to the advantage of the led. --Bergen Evans
