- Be polite and concise.
- Ask for what you want and explain why it's reasonable.
- Don't ramble on about irrelevant details or sound like a crazy person.
- Use spell check.
- Don't make empty threats (they know you won't sue over $200 and they probably don't care if you never stay at their hotel again).
- If that fails, you could mention that you don't want this isolated incident to prevent you from posting a positive tripadviser review.
- If you happen to be a lawyer, attaching your business card ("to provide contact details") usually gets a result without having to make any actual threat
