Yep, hope they're not getting confused by all this.
The price quoted or seen on the website consists of two fares; the cruise fare and the non-commissionable fees (also known as port fees). The taxes (or referred to on some sites as taxes and fees or as taxes and port fees) are shown as a separate price.
Again, this is why it's best to book with an agent so they can give you all the prices and you can see what the total cabin cost will be. Then they can also advise you of any other fees that you will/may incur; gratuities, transfers, baggage fees, specialty restaurants, etc. etc.
Plus, they can also give you other options to consider, especially to Alaska since some cruise lines go places others don't, such as to Glacier Bay.
