Felix ok if a cruiser can't travel the day before. But if you are flying to the port the same day during hurricane season you better get insurance.
You can presume that some flew in the day of, and they arrived too late. But I'd bet there were also those who were in the day prior, and spent their time touring San Juan, and arrived after the ship sailed.
RCI DID NOT even make an attempt to contact passengers... so let's not pretend they handled this well.
They did the very minimum necessary according to the contract.
And the people who were left behind had to be plenty worried, standing at the pier where a ship should have been, with a hurricane heading to the island, which was why the ships were ordered to leave.
