I think that you will find that the excursions for the Sea Princess in the Caribbean in 2009 will be exactly the same for each port of call as they were in 2008. These excursions should be available to review somewhere in Princess Cruises literature right now. You will be sent an exact list of excursions that SHOULD be available on your particular cruise, together with other essential literature, nearer the departure time of your cruise. You will have plenty of time to look at this and book then if you wish. Happy cruising.
The Sea Princess does a 19 repositioning cruise on 13th October and from 1st November leaves from Barbados so that will set the time for this information you are seeking.
Go to www.princess.com, select the tab 'Learn about our Cruises', select shore excursions from the drop down menu. You can then select Caribbean and the ports you will be visiting (both drop down menus). As stated by Burrows these are current shore excursions but they should be more or less the same for 2009. Nearer the date of departure you can either book your excursions on the Princess website or on the booking forM which they will send to you. Just bear in mind that it can be cheaper to pick up a local taxi (and there are plenty at each port of call)who will take you wherever you want to go. Enjoy your cruise.
You should get a brochure about 10 to 12 weeks prior to your cruise with the relevant trips this will also show the cost of each trip (in $). But if you log into the Princess web site with your booking ref. no. use the cruise personaliser (found under Prepare for your Cruise) and you will be able to book your trips on line, when they become available.
