On embarkation day, Disney Cruise Line staterooms are typically ready between 1:30 PM and 2:30 PM. While you can board the ship much earlier depending on your assigned Port Arrival Time, the stateroom hallways are often cordoned off to allow the custodial teams to finish cleaning. During this "waiting period," guests are encouraged to head to the upper decks for a buffet lunch at Cabanas (or Marceline Market on the Wish and Treasure), explore the youth clubs during Open House hours, or even jump in the pools. It is highly recommended to keep your swimsuits, medications, and important documents in your carry-on bag, as your checked luggage may not be delivered to your cabin door until late in the afternoon or early evening. Once an announcement is made over the PA system, you can head to your room to settle in before the mandatory Assembly Drill.
