Reasonably (though still a bit dear) priced 14 night cruise to the eastern Caribbean in a balcony cabin, boarding at Castries, St Lucia on the Britannia, visiting 9 islands in total, mainly in the Lesser Antilles group.
First timers with P & O, though had cruised several times with Celebrity X and once on Royal Caribbean.
Good flight out on a chartered Thomas Cook Airbus A330 (I think), disappointed to find that although flight time was about 1.25 hours less than scheduled, had to sit on plane for about that time or longer without full ECS, because buses weren't available to take us to the ship until the scheduled time. Why we weren't allowed to disembark and wait in the airport I guess was down to the rather small size of the airport and its limited lounge facilities, though this was rather uncomfortable given the temperature and following the long flight.
Felt cabin was a little small, same goes for balcony and bathroom.
Cabin steward was excellent.
