the cruise starts in Seattle, goes to Russia (2 stops) down the coast to Korea, China, S'Pore, Vietnam, Indonesia and on to Australia, Fiji, Samoa, Hawaii and ends in San Diego. Lowest ocean view price is about $11K per person. You would need to get several visas and immunization is recommended.
I have taken several cruises on the West Coast, Alaska, around Latin America and to Antarctic and down the Nile.
I have been on several different lines, all were fine, no problems, but overall I prefer Holland America with their smaller ships.
Let me know if this would be of interest and any other questions you may have.
