My wife and I are 60ish. This was our fifth cruise, with three different companies -- our second Princess cruise. It sailed from Ft. Lauderdale FL, from March 4 - 11 through the eastern Caribbean with four stops.
Princess managed to make the beginning of this cruise as awful as air travel. But the experience improved after a few days.
We received an email a few days before March 4, advising that embarkation was delayed to 3:00 PM due to a noro virus outbreak on the previous cruise. We had to be out of our hotel by 12:30 PM and had our shuttle pre-booked so arrived at the terminal at 12:45 PM. We walked onto the ship just after 5:00 PM -- it continued boarding for about an hour and sailed just after 6:00 PM.
