Tarbat,
Met some friends in Glasgow who are on the cruise. She left Southampton went to Leith then round to Greenock. She sails tonight to Liverpool, then goes across to Cork before heading to Cherbourg and back across to Southampton. Each passenger is given a credit card size swipe card which they use when leaving the ship and again when returning. Nobody is allowed on board without this card therefore, unfortunately, we could not have a look around her whilst she was docked in Greenock. All to do, quite rightly, with security. Indeed, on boarding all passengers have to go through a security scanner similar to those in use at airports.
Apparently, she caused the surrounding streets in Greenock to become gridlocked with sightseers.
