I'm from Hong Kong and went with my parents to our first cruise in Apr 2013. Since it was not the busy season yet, the price was lower than cruises in May-Aug. Overall it is a good experience with Regent.
Embarkation and disembarkation
We embarked after having lunch in Venice near the port. Overall the process was smooth. There was sufficient staff there to help. We are in our stateroom in less than an hour.
The cabin steward knew our names and was always around, and when he was, he would open the door for us. The stateroom was clean, spacious and beautiful and there was sufficient room for 3 people. The walk-in closet was large. Bathroom amenities were replenished very quickly. The sliding door to the balcony was a bit difficult to open but we managed to do so.
