I noticed that too, CruiseFanatic. The surcharge for our upcoming 7-night cruise on HAL for my family of three will be between $70 and $140 (taking the $10 pppd cap into consideration). On NCL, it would be $119. Of course, as billybuzzy pointed out, NCL is not applying the surcharge to existing bookings. (I wonder if there will be a rush on NCL bookings in the next two weeks...)
Here's the official press release
from NCL for those who haven't seen it.
