It's a very festive thing to do on a Christmas cruise and is fun.
I usually go round and collect all of the chocolate Santa's and put them outside a friends door.
It's always a good surprise when they get up and open the door in the morning.😁
Your right buy Silversea do have some interesting itineraries.
NC offerings are not good neither Regent.
Explora won't be that interesting until more ships are sailing.
