We were recently on a 9 day on the Grandeur that ended June 8th and on that cruise I played for maybe an hour or more on several days and lost around $120.
The background - I gamble some, mostly on cruise ships (my only opportunity usually).
While I hesitated to post this, my curiosity was so great that I decided that I just had to know more and I hope those who frequent this forum can help me do that.
