We enjoyed the Mariner of the seas ship, a tad bigger than the two P&O ships and was in ore of its size. We booked and inside cabin and we were happy with our room, although we had a little of room envy when we passed the Balcony cabins, you get what you paid for. Over a thousand passengers were of Asian decent and this culture that this community of people are used tom that is jamming into lifts and pushing through crowds was a little over whelming for me. This could have been addressed with ships crew manning lifts to ensure that manners were kept inline with Western culture, We did not use the pools, but there were plenty of spa's and pools to choose from. The Windarring Bisto was ok, with plenty of food. The main restaurant was stunning, the food was ok, but we were quickly served and knew it was time to leave for the next sitting. The shore tours were reasonable and decided to use them, being so far from Bangkok and Saigon city both over 2 hours bus trip each way, don't take the risk with a taxi. Compared to the smaller ships we have been on, we enjoyed the P&O better that RC. The hospitality lacked with Royal C. The entertainment was excellent, but only 3 shows out of 7 nights. The casino is large and smoking allowed, so much for health regulations.
