If you look to the left of the screen you will see a list of cruise guides for 1st time cruisers go through them top to bottom it will give you some idea what cruising is like.
Hope you got some answers to your questions. I suspect that P&O havn't finalised shore excursion details yet as they do not visit these ports very often. Email me at firstname.lastname@example.org if more info if you want. Regards,Ex Kiw.
