We chose this cruise for the itinerary and dates. We have never cruised with P and O before and are unlikely to do so again. We upgraded our flights with TUI which was money well spent. We were through check-in and security at Gatwick in no time at all and the flight was very good. Transfer to the ship was also good. Our cabin was ok,the balcony and bathroom were smaller than we have experienced on other ships. The muster drill was a complete shambles. This cruise has people embarking at different times and in two different ports, therefore when we were called for our drill there were people trying to enjoy a drink in the bar area that we had been assigned to. This was exacerbated when we tried to get back to our cabin. Everyone was trying to get to the lifts at the same time, and there are no stairs by the middle set of lifts. The design of this ship is frustrating, having to go up a couple of floors and then down again to get to another part of the same deck is beyond belief. Dining was a mixed experience: the Horizon self service or the 'push and shove' as we called it was poor, food selection was poor, very few staff available for drink orders, therefore we rarely ate in there. Peninsular was ok for lunch, Meridian was ok for dinner, Oriental was our choice for breakfast, service however was slow. Epicurean was not worth the money, chewy steak! Sindhu was excellent. Limelight club was very good and the Glass House was excellent. The entertainment in the Headliners theatre was not to our taste. Shore excursions were very good, enjoyed the bike ride in St. Maarten, and the Caribbean cuisine in St. Kitts.Overall an enjoyable cruise.
