Travelled in a group of 4 adults aged 40-50, yes we were some of the youngest on board but that didn't affect our enjoyment. We were a bit nervous about the 4 days at sea each way but we really enjoyed the time we had to relax, we were lucky with the weather , although it was cloudy first thing in the morning most days the weather became sunny and warm. As soon as you reach the evening of day 2 at sea you notice the difference in the air temperature it warms up considerably. We had one evening where it was a little choppy but again nothing to be concerned about I have experienced worse in the med. The Golden Princess is a lovely ship and these were the best inside cabins we have experienced in regards to size and layout. The food was good in the main restaurant, we had anytime dining which was brilliant, all you had to do was notify them that you required a table and for how many people and they would issue you with a buzzer they you could take to the bar and it would buzz when your table was ready, the longest we waited was 15 minutes.
The buffet food was ok but not as good a selection as royal caribbean and celebrity. We bought a soft drink package, which worked out about Â£5 per day and was excellent, you could get drinks everywhere and they included fruit juices, sodas, all non alcoholic cocktails and hot chocolate and you didn't need to buy one for everyone in your stateroom.
Hygiene on the ship appeared to be excellent with cleaning crews always washing down hand rails and common areas, hand gel available in the restaurants and all main doors to toilets had hand towels and bins beside them so that you didn't need to touch door handles.
One of the downsides was the entertainment, not the quality of the shows themselves but the fact that they have made all of their shows 30 minutes, so you spend a lot of time being herded from one venue to another, sitting down for 30 minutes and then moved on to the next. I appreciate the need to allow everyone the opportunity to see all the shows but in fact what was happening was that people didn't bother going as they new they would have to move again in half an hour and particularly for some of the less mobile this was a problem.
Hawaii itself was lovely the islands and trips were excellent, we did the trip to Pearl Harbour and the Whale watching both of which we enjoyed.
My major complaint would be why on earth did they make Ensenada in Mexico a stop ???? There is nothing there and no reason to get off the ship, it is not a tourist area and is very run down. Considering we spent 4 days at sea getting to Hawaii an extra stop there or and overnight stop would have been much better. Everyone said this and Princess really need to take this into consideration. Something tells me there is a business reason for this stop and it is not for the benefit of the passengers !!
All in all a good cruise , still prefer Royal Caribbean but would go with Princess again and would now consider more days at sea.
