Awesome boat! We had a stag party of 20 men. The boat is pretty huge and we never felt cramped. The communal area is really nice. It feels a bit like your sat in a lovely pub. The boat was docked in Noordalicht, which is a very cool, hipsterfied area. There was a restaurant and bar within a minutes walk from the boat. I'd definitely recommend other large/stag/hen groups to follow suit. Way better than any hostel.
