Notes on these figures
CruiseMapper lists the identical 292 slots / 17 tables for all five Voyager-class ships, so it may be a class-level figure rather than a ship-specific count.
CruiseMapper says the casino was renovated with baccarat and sic bo tables, and the Golden Room (upper level of the disco) became an invitation-only VIP casino lounge also used for high-stakes poker. Table-game list is CruiseMapper's generic Casino Royale description (also lists video poker machines); not a ship-specific inventory.
