I wish to give 4 starts, they almost deserve it, but they have a peace of "real Dutch business in its bad way":
It doesn't matter what ____ [take from list below]:
- it is summer
- long days, short nights (like in June)
- it is a beautiful weather
- there is a demand from customers (not only my group)
- it is a weekend
their running hours are UNTIL 20:15 (and not for all type of boats as they start to park them from 20:00)
If you want to leave your work and spend evening with friends by taking boat in Leiden - it is not your choice unless you leave work at 16:00 and you already in Leiden.
Fortunately, they are not the only boat rental in Leiden. There is another one 250 meters away.
Guys!
Extend your working hours (at least till 21:30, may be only for advance (24h) booking, so you will be more comfortable with stuff planning)
