I am not sure which cruise line you are going on let alone which cruise as we are not the agency side of this page but to book the ship's excursions you can normally do this by going to the web pages of the cruise line concerned and following the sections for excursions. You will probably need the reference number given to you by the cruise line.... Neil.
Hi there if you go into your cruise lines official web page there should be a part that says cruise personeliser if you click on to this it should ask you for your details and booking ref, once you have done this all of your details should come up go to shore excursion and you should be able to read and book before you go.
i have done this many times with p&o and also princess good luck and have a great holiday.
