I don't know the Orleans comp policy for table play but when I was at the Four Queens it was $25 bets for 4 hours a day to get room only comp.
Strip properties are higher.
Its not how much you play its how long.

Slots give you points that can be converted to room charges in most casinos.

Most hosts will tell you to come in and we will rate your play. Unless you open a BIG credit line.
