I remember many 11 pm sailings! We’ve had 2 held, both til after 1 am. The first time, 23 years ago, was on our very first cruise, because a winter storm on the mainland delayed a lot of flights inbound to SJU, and the first port was Aruba, with a sea day before that, so they held the ship. The second time Radiance needed a gas turbine replaced, which required extra time for installation and testing. Both sail always were so late the city and fort lights were all dark by the time we left.
