There are cabins available for the August cruise. If you check back on June 15th, there could be more and also on June 20th. These are the 75 and 60 day payment marks. Many people have cabins reserved, but will not be able to make final payment, so some will open up. Runours are that
DCL will be looking at additonal US Ports for future sailings, as popular as the west coast cruise are for this summer, it wouldn't surprise me to see a third ship eventually serve that market year round.
DCL does off some special 10 night cruises from time to time, and if you are really, really, really wanting 14 nights, book either 2 7 nights back to back on the Magic or a 3night/4night/3 night/4 night on the Wonder.
