Excellent Setup, great way to see Holland.
Weather always a risk in Holland. It was cloudy, cold-ish, sometimes wet, and quite windy (but the following week, after our tour ended, was perfect with not a cloud in the sky.) The tour is well planned and you see different parts of Holland. We knew of course about the water ways, windmills and such, but we did not realise Holland is basically a swamp...
Bikes are very good and crew on the boat and tour guides were very friendly and helpful.
The soccer world cup was a bonus (being soccer mad), and provided excellent entertainment from our perspective. But I would suggest planning your social activities on/off the boat in advance as there is no entertainment - it's not a Caribbean cruise :) There are a few cruise legs in the evening so you can't really get off the boat.
Food is good, the bar is good - buy an open bar ticket if you like a drop, it is cheaper that way.
One surprising commission is a laundry facility on the boat, or at least dryers, and no information on an alternative off the boat. In any case, who'd want to spend 2 hours in a laundromat off the boat? They ought to have a facility because naturally you go through a lot more clothes in a week of cycling, especially if the weather is not kind to you.
Most people were "senior citizens" on our tour, myself included (but I was an outlier in my family group). So bear this in mind if you look for younger company. Choose a harder tour if you have keen athletes in your family. I was with three in their 20s, all fit and eager (I'm 60+). They formed a breakaway group a few times. I decided to stay with the peloton and give chase later. I soon discovered it does not work with a peloton of one rider.
