Yes, most cruise ship casinos in 2026 still accept physical cash at both the tables and the slot machines, but the industry is rapidly moving toward a "cashless" ecosystem. When you sit at a table game (like Blackjack or Roulette), you can hand the dealer cash in exchange for chips. However, for slot machines, many lines now require you to insert your "Room Key" (or SeaPass/Sail & Sign card) to "load" credits. You can fund your room account with cash at the Guest Services desk or at a kiosk in the casino. A "pro" warning for 2026 travelers: if you use your "Room Key" to withdraw "Charge to Account" credits at a slot machine or table, many cruise lines will charge a 3% to 5% convenience fee. To avoid this, "pro" gamblers bring a set amount of physical cash and use it directly at the tables. It is also important to note that most cruise casinos operate in U.S. Dollars, regardless of where the ship is sailing, and any winnings are usually paid out in cash or as a credit back to your onboard account which can be cashed out at the "Cage."
