So, you're right, NCL does charge more.
But then again, NCL usually goes to more ports.
Even Carnival and Royal Caribbean charge different taxes and fees mainly because they go to different ports.
The only port in common for all three ships is Cozumel.
Let's see what the others would be if we added an extra port, assuming the same tax and fee rates for the extra port:
$36.10 x 1.33 = $48.01
$38.67 x 1.33 = $51.43
How much more expensive is it?
$60.69 - $48.01 = $12.68
$60.69 - $51.43 = $9.26
I wouldn't be crying over that, about the price of two drinks. Much ado over nothing!
