I just completed Oceania's Asian Wonders cruise on Nautica January 15-30, 2011. I am an Oceania groupie and love the ambiance, excellent service, exceptional food, and the type of clientele attracted to Oceania. I have cruised on all three small ships over a period of 6 years.
I chose Asian Wonders because I specifically wanted this itinerary, and was not disappointed. Be aware that going to Hanoi is a long 3 ½ hour drive from the port each way making a long day and a long drive. Destination Services offered an overnight in Hanoi -- a better time management option. Otherwise proximity from port to city was not excessive.
When shipboard changes occurred in the past it was usually a positive change and often not noticed by guests. However, I was disappointed to experience the change in management of Oceania@Sea. I immediately expressed my feelings to the concierge about this.
B1 Veranda Cabin on 6th floor, three doors from aft elevators. It was amazingly quiet. I never heard any traffic or people in the hallway. Turned out to be a great convenience to be near the elevators and stairway. This cabin was identical to A1 cabins I've had in the past. Let us not overlook the fact we are on a ship, thus, I did not find bathroom space to be limited in the B1 or A1 category.
