We had the same on our last cruise out of Norfolk in August. We are platinum, my daughter gold and we had a newbie couple. I got 11, my daughter got 11:30 and the newbies got 12:30. We got there around 12 because parking took so long but they sent us right through in the platinum line and there was a line for early arrivals. Just take the early time and go with them. Don't know about other ports.
