This was our 2nd cruise and our 1st with P&O
We opted for a "Seaview" room (rather than a balcony on our previous cruise) and we paid slightly more at the time of booking to be able to pick pick our cabin.
We chose a cabin on a low deck towards the centre of the ship as we were cautious of how rough the North Sea could be in September and wanted to try and reduce the chance of use getting sea-sick.
