Our family of 4 (2 adults, kids 15 and 17 years old) spent 14 nights over Christmas on P&O's Brittania, when we sailed to 8 Caribbean islands. The cruise was superb.
We have previously sailed with Cunard 6 times (on all 3 ships), have done a 2 night Celebrity cruise on the Eclipse & have done 5 short cruises from Southampton on P&O's Ventura, Oceana & Aurora. Although our P&O short cruises have been fun we have not been impressed with the ships or food and the service hasn't been as good as Cunard.
We booked this cruise as the island itinerary looked interesting, the dates were good for the school holidays and the price very reasonable compared to the alternatives.
Good position on the ship.
Just walked into town. Pretty but would do an excursion next time.
Bus for $5 to Eagle Beach. Sunbed $5 each which we positioned under a tree. Would get there earlier next time to get a beach shade. Pretty beach, not too busy. Good restaurant opposite the beach.
