Dear __________,
It was so wonderful to have a chance to visit with you this week. You are always such gracious hosts. We appreciated being able to stay in your lovely guest room, and we greatly enjoyed all of the delicious meals you prepared for us. Thank you also for taking us out on tours of the area. Your country is absolutely beautiful, and there are so many fun and interesting spots the average tourist would never find on their own. It was exciting to see and experience a bit of how the locals live and play. I hope the next time you travel to the USA you’ll plan on staying with us. We’d love to reciprocate your kindness! Thank you again for everything.
Many kisses,
(YOUR NAME HERE)
