We are going on the Countess in April on the Paris/Tulip cruise. We sail from Amsterdam after 3 days in Paris. I am trying to find out how long it takes to get from the river port to Schiphol airport as we are taking the high speed train to Brussels where are friends will meet us. I am concerned that I haven't allowed enough time. Hopefully someone on the boat will be able to help me. We will be spending a week in Belgium and then returning to Amsterdam to fly home.
