Effective August 2nd, there is going to be a change to the operational hours of the
Disney cruise terminal in Port Canaveral. The terminal and parking garage will open at 11:00 AM.
The port arrival times under My Online Check In have been adjusted. If guests arrive earlier they may be asked to wait until their scheduled time before they can enter.
If guests are traveling with another family and the earlier time is gone it is suggested that they all check in at the later time. If guests dont select an arrival time online they may be delayed entry into the terminal until guests with assigned times are accommodated
