I've not sailed on Navigator butI have never found any problem changing money on board any RCI ships, they sometimes have a local bank aboard, In the main I try to take US Dollar TCs with me and these they will cash dollar for dollar on board. Unless we are in a Euro port you can invariably spend US Dollars ashore with no problem. As far as bridge is concerned there has always been a bridge club on each RCI ship I've been on with normally two professional in attendance you find it mentioned in the ships daily news. I cannot say whether there's a charge because I prefer to be more active (and do the quizzes) Neil Dow.
No problems re currency. Regards bridge,see crew who can help to put a notice in library to organise a game.
