Book Excursions PRIOR to the cruise
 

I've read this can be done on some lines, can anyone tell me if Carnival is one? If so, is there a different phone number?

Royal Caribbean, Celebrity and Princess allow this.<BR><BR>I am not sure of any other lines that allow this.

According to the Carnival website, it sounds like you can only book excursions once you are on board.

HAL also allows on-line excursion booking. All my September Amsterdam excursions are booked and paid for.

NCL also allows you to book your shore excursions ahead of time, on-line.
