I need to write a letter to a friend about my recent vacation. Can you help me with that? The response should contain 3 paragraphs. Paragraphs are separated with the markdown divider: ***. The response must have 2 sections. Mark the beginning of each section with SECTION X, such as: SECTION 1. Your response should contain at least 2 placeholders represented by square brackets, such as [address]. Include keywords [details], [hotel], and [sights] in the response. Finish your response with this exact phrase [ender]. No other words should follow this phrase.
