How long will it take for the hotel to get the money back if it sues for late payment?

It's an economic dispute, so I suggest you bring a lawsuit directly to the court. Prepare two indictments, one evidence and one identity card, and file a lawsuit in the court where the defendant is located. If the other party continues to refuse to repay the loan after the judgment of the court, it is an act of dishonesty, and the court may also include it in the list of untrustworthy people for three months.
