If you missed out on Norwegian Cruise Line's one-day sale yesterday, you're in luck. It has been extended into a three-day sale and now ends tomorrow, Saturday, March 28. Advertised per-person savings can be $400 to $2,000, with starting prices as much as 79% below regular rates on select sailings to Alaska, Hawaii, the Caribbean, and Europe.

Note: Sale prices only apply to the first two passengers in a stateroom, so a family of four could quite easily end up paying less by booking two cabins. Use code PG1Day when booking.
