Family cruise on Norwegian Epic
This column says NCL just doubled the prices on Cirque Dreams & Dinner to $30 and $20 (for $15 and $10).
As I said - the truth is that they had to feed you anyway, so in fact you are paying for the entertainment.
I voted that I would pay a small fee ($5) for a reserved seat in a front row that I did not have to stand in line for. But I like good seats. I also usually try to get the best seats I can for any show on land, it makes such a difference.
