Embarkation for a Disney Cruise typically begins around 11:00 AM or 11:30 AM, but your specific entry time is determined by the "Port Arrival Time" (PAT) you selected during your online check-in. Disney is very strict about these windows to prevent overcrowding at the terminal. If you arrive earlier than your assigned PAT, you may be asked to wait outside or in your car. Once you are cleared to enter the terminal and complete security, you are assigned a "Boarding Group" number. Boarding usually starts with Concierge guests and Platinum Castaway Club members first, followed by the numbered groups. By 1:00 PM, most guests are on board and heading straight to the Cabanas buffet or the pool deck for lunch. It is important to know that while you can board early, your staterooms are usually not ready until 1:30 PM or 2:00 PM, so it is wise to keep a day bag with your swimsuits and medications while the crew delivers your larger checked luggage to your door later in the evening.
