The San Francisco port of departure is very popular and common in general. You needn’t be concerned about making reservations for an Alaskan cruise that leaves from San Francisco, because that is actually quite simple to do. Many of the most popular cruise lines heading towards Alaska offer you the choice between several ports. If you find that perhaps traveling to Vancouver or even Seattle is too far for you to go, than you it is usually simple to find a cruise line which departs out of San Francisco as most of them do.
In the peak season of April to September, Princess Cruise Lines has lots of cruises to choose from. Their San Francisco prices are a little higher due to how far north you will be travelling on the ship before you reach Alaska. Because departing from Vancouver requires less time at sea and provides more time to explore the pleasures of Alaska, some people find it preferable.
As already mentioned, Royal Caribbean also offers cruises that depart from San Francisco during the best months of the year. All of these cruise companies have reduced fares for last minute travelers or for less than spectacular board on the ship.
