This was our 10th cruise with Princess and we definitively enjoyed ourself on this trip very much. Having been to Japan before, the cruise itinerary gave to us the opportunity to visit backcountry areas which normally we would not go to on ourself.
The Diamond Princess, in fact not the newest vessel anymore in the Princess fleet, still was in very fine for us, the balcony stateroom is on the smaller side but offers enough space for the limited time we spend there.
The staff was really excellent, wheter it was our stateroom steward, the waiters in the main dining room and at Horizon court or at any of the shops - very obliging and helpful.
Of course you can always find this and that what could be brought to perfection, but Diamond Princess still offers great value for your money.
Our only major complaint was the repetition of the food menu after one week - so all guests staying on board for more than 8 days all the food selection from the first week was repeated in week to.
In summary, we had a great time and will definitively cruise with Princess again.
