We found a great Norwegian Cruise Lines sale for the West coast (Vancouver port).
Must book by July 19, 2013.
This cruise below is as low as $279 (inside cabin)!
5 Nights Pacific Coastal Cruise from Vancouver to Los Angeles
Ports of Call: Vancouver, British Columbia; Astoria, Oregon; San Francisco, Ca; Los Angeles, California.
2013 departures: Sep 29
This is a great price for a short cruise.
They have other cruises in September on sale.
