Oh Great ! It's nice to hear that another member is up with the cruise industry to some degree ! I understand it's rebounded since the slump during 2020-21 or -22. Thus justifying a gigantic ship like this. Before there were megaships, but Icon of the Seas outclasses them all.
You're right of course, especially considering it's Royal Caribbean [ a not very good line. ] But, let me tell you, I was once on a Renaissance ultra-ultra ship which went from Bombay [Mumbai] through the Suez Canal, ending in Alexandria, Egypt and finally Venice.
On that, there was a Greek Orthodox woman who was frantic to get to St Catherine's Monastery, Mt Sinai. She offered to charter a helicopter with me to visit the venerable monastery from the nearest port. I was eager to go - until I heard the price ! I tearfully had to let her travel by herself. She said it was fantastic to see St Catherine's.
So - i bet this pilgrim had at least one Icon aboard - !!!
Actually, some cruises include places like Meteora [ i saw that too from a cruise ship ]. Probably St Catherine's didn't have a real gift shop on the premises, but Meteora and surroundings certainly did ! I brought bac a few Icons ; i'm sure a number of other passengers did, too.
So yes, Icons DO go aboard and travel with cruise ships. But whether Icon of the Seas will boast any is not sure. I don't know the vessel's scheduled routes, but I assume they will be in the Western Hemisphere.
I think a beautiful Icon of the Mother of God, maybe like the one i posted above, would be ideal on either side of the top of the bow...
