Dear [recipient's name]:

Welcome to all of you who are attending the 5th annual Davis family reunion! We are so happy that you have joined us for this fun-filled, exciting, memory-making long weekend here at the beach. Enclosed with this letter, you’ll find a brochure detailing all of the events we have planned.

Make yourself at home, and let's get ready to relax and enjoy the time we have together. Again, welcome!

Sincerely,

[Signature]
