On the casino offers that require a deposit, it is still a $400 deposit, which they receive back as an onboard credit once the cruise begins. Sometimes as ships start to fill up, there will not be any single-capacity cabins available, but the casino program comps are based on double occupancy cabins. This means that comp solo travelers don't need to worry about being restricted to single occupancy capacity.
