The Stena Trader terminal is already in SS right? I don't think the DFDS terminal at Vlaardingen and the Stena one in the Beneluxhaven are really needed because the terminals are purpose built for ships that aren't in the game.
Vlaardingen would be interesting, especially on MP watching people trying to take PoR in there, I wonder if SSE will have tides???
Clanky, the Maas and Humber Viking which berth at Vlaardingen have a draft of 6.5m, the POR has a draft of 6.05m so why would there be a problem getting the Pride in?
Sorry about deleting my post above, didn't mean to make it confusing
