From the beginning when boarding people were forced to wait in a line that stretched around the building and across a main street in the hot sun for hours. No food, water or shelter from the sun was provided until very near the end - this could have been tragic for elderly folks if it were hotter.
Once on board they went into their sanitation mode, removing salt pepper, butter, rolls etc from the table. In the Cafe they removed all the trays and served everything to everyone individually. These should have been good things but the crew was totally understaffed, overworked and untrained. Ask for salt and wait 10 minutes, want more water - forget about it until after dinner. In the Cafe try balancing a dinner plate and a salad plate while waiting 20th in line for a drink, trying to find your spouse, and then looking for a non existent clean table.
Guests got angry and the crew got surly, many standing around not knowing or caring what to do next. It is incomprehensible to me that there was not a viable contingency plan in place for this sort of thing which is a well known potential for any ship.
Bad planning, bad execution, bad ship, bad management, bad cruise line
