Donna's question about San Juan is mine, too.
It was so great just to dump the luggage and spend a day in wander mode "at home".
I wonder if this is a question of convenience or security? I'd assume that if nobody's luggage had blown up on the ship, it's not likely that it's going to blow up post-cruise.
I can understand pre-cruise, pre-flight scrutiny. But at the end of a cruise? It seems safe enough to me.
