回复：谢谢回复。还有些问题

many web site offers that, you can try with www.cruise.com, or kayak.com, etc. I also found web site like: http://www.lastminutecruises.com/, though I am not sure the reputation of that site. If you purchase deal through those web site, they become your agent.

Alaska cruise price varied, depends on cruise company, itinery , etc. However, for Pricess cruise, from Whitter to Vancouvar, depart mid of June, 7 days, inside cabin, normal price is first 2 persons, around $700 per person, the 3/4 person, around $550 per person, plus tax/surcharge, 4 people price would be around $3000 totally.

Hope that helps.
