We thoroughly enjoyed our Princess cruise (family of four including two teenage girls - 14 & 16). The flight from Gatwick to Montego Bay, Jamaica was an ordeal (as is any long haul flight with fairly budget airline) but we survived.
We had two inside cabins next to each other on C deck which we fine - very clean and quiet and our steward, Mel was a lovely chap and very helpful and friendly. I smuggled a bottle of gin in our suitcase and he provided us with ice on a daily basis.
On previous cruises our children have barely spent any time with us, making full use of the children's club, but this time they stayed with us the whole time, enjoying everything just as much as us and we had real quality family time. On the last day I suggested we did Orlando the following year and they both said they'd rather do Sea Princess again which I think speaks volumes!!!
Nice inside cabin - pretty quiet although could sometimes hear neighbours.
