Hello WINEoS!

Just curious, how are you getting to Southampton on 8/19? We'll be in London for 3 days before the cruise and are thinking of taking the train that morning( Waterloo station to Southampton). There are two possibilities I'm looking at: either arriving at 11:12 AM or 1:15 PM. I would rather take the earlier train but don't know if getting to the ship before noon would be too early. Anybody familiar with embarkation at Southampton?
