Hi [Friend's Name],
Greetings from [Location]!
We are having an amazing time here. The weather is just perfect – sunny and warm. My family and I are staying at a beautiful beach resort. During the day, we swim in the ocean and build sandcastles. In the evenings, we enjoy delicious seafood at local restaurants.
Wish you were here!
Best,
[Your Name]
