Think yourself lucky if you got on the 23:05.
I couldn't get on it. Got on the next one, and we all got told to get off after a few minutes and go back and get info for the next train. Got on the next train, which after being on it for what seemed an eternity, didn't leave the station because of a problem with the doors. Eventually got on another train, didn't go all the way to Southampton, we had to get off at Basingstoke and get a bus to Southampton.
Got home at 4am. Never again.
