I ran this as a small adventure within my campaign, and it was a huge success!!
My players had an amazing time, absolutely loved everything. I highly recommend to any other DMs make as many props as possible if your players are props people this is a winner!
I made little pages with all the notes on them. Handed out drink tickets (I modified it so that every player had to win a special drink ticket for the special cocktail through various casino games, and then provided real cocktails to the winners)
a super fun and a little silly romp through a casino with puzzles and clues all around - worth running!!
