The correct answer to this question is , "it depends."
There are many cruise lines that sail from Seattle, WA to Alaska. Sailings start in late April and go through mid-September. Some sailings are round-trip and only go as far north as Glacier Bay or one of the fjords (e.g. Tracy Arm), while others are one-way and end at one of the ports that serves Anchorage, AK (Whittier or Seward). Sailings are cheaper at the beginning or end of the season and most expensive in the middle. The reason for this is the temperature. Obviously, it is warmer in July than it is in April!
Price also depends on the cruise line. For example, the same itinerary on Disney will be about twice the cost as on Carnival. Prices also vary from year to year.
So, the best answer is to call you travel agent and ask what it would cost for the sailing that you are interested in.
It all depends on cruise company, time of year and room category.
