This is a tough question! Some of my favorite memories come from different travel adventures. If I had to pick one, though, I would have to say the time spent with my homestay family in Nicaragua, while visiting Unearth the World's Sustainable Tourism partner there.
They were such a warm and welcoming family! I loved sharing meals with them, watching TV in the evenings, and practicing my Spanish - they were very patient! I felt like I learned so much about the culture and local community through their generosity, and willingness to open their home to a stranger.
If you ever have the opportunity to participate in a homestay while traveling abroad, I would highly recommend it!
