Just me...

Is the money you use in the casino a separate "pot" of money, or does it keep building up on your room charge? For example, let's say I don't want to lose more than $500. in gambling expenses on my trip. Will it stop once the $500. runs out, or will it keep adding debt to my room charge (hence, credit card), running the risk of, say, a $2000. charge to my account? Thanks! 🙂
