We've been on Windstar, Viking, Peter Deilmann, Paul Gaugain, Grand Circle, and a few others but our recent trip with Uniworld for the Tulips and Windmills cruise was the best.
While the cabins were small, they were very well organized, beautifully appointed, and quiet.
The crew was outstanding, from the cabin stewardess to the captain, the guests' comfort, needs, wants, and satisfaction were a priority.
The tours were well run, well organized, and most were included. All tips, including bus and tour guides were included as was all alcohol and some of their "standard" brands were what would have been upgrades on other lines.
We keep looking for another cruise that goes to where we haven't been yet because we would most definitely travel with Uniworld again!
