we choose this cruise because we had heard good things about Regent and we liked the fact that it was all inclusive.
We liked the ship itself. It was clean and well maintained. We did not like the pool because it was too hard to get into and out of.
The concierge level cabin was nice. The bathroom had both a bath tub and a separate shower and we liked the fairly large walk in closet. We also liked that there were drapes not only on the windows, but between the sitting area and the bed area. That allowed one of us to sit and drink coffee and read without waking the other. Since the only differences between concierge level and penthouse level seemed to be that the penthouse level had a butler and nicer bathroom amenities we didn't see the need to spend the extra few hundred dollars for the penthouse level since the rooms are the same size.
Nice cabin. Walk in closet and both a shower and tub in the bathroom.
