They have been allowing boarding as early as 11 AM on the east coast cruises if the ship is cleared through Customs. They have been handing out flyers in the embarkation line saying Welcome Aboard, and directing everyone to the Lido Deck for lunch. The cabins are closed off, and the flyers say that the cabins should be ready by 1:30 PM.
Just wanted to pass this along to any early arrivals at the piers!
The official boarding times are listed here.
It sure beats waiting in line.
