It was a wonderful cruise, but no Mah Jongg.
No set in the game room and didn't find anyone playing. (I've been know to hang around a game on a ship, in hopes that they'll ask me to sit it)
I think if I had taken my set and put it out in the game room, I could have found some players. I agree with Donna. They should have a bulletin board somewhere (maybe the ship library) where you could post that you were looking for players!
There were almost 2400 passengers on the ship. There must have been some Mah Jongg players!
