If a person goes to a hotel to spend hundreds of thousands of dollars with illegal money, should the hotel refund the money after chasing it? I spent all my money on the party.

A hotel is a place where people can serve and spend. When others spend there, the hotel has no obligation to find out whether the consumer's source of funds is justified. Therefore, even if the illegally obtained huge amount of cash is squandered in the hotel, the hotel should not refund the money when the judicial authorities investigate it.
