We were on the Eurodam. We had no idea about the blockade. But we had to be back on board by 230 for a 3pm sailing. Left orient beach about 1230 and our taxi driver told us the blockade was coming soon. Traffic was heavy but otherwise fine. So folks on a ship sponcered excursion from our ship got stuck in marigot and took a water taxi back to the ship which was held about an hour for them.
