Invite guests to enjoy food and show videos and movies from a place that was visited.
Lisa from easy-party-ideas-and-games.com says...great idea! We did this with some friends 10 years after taking a big trip together. We had a little reunion of those of us who went on a trip. We showed a video, ate food for that region, and looked over our old photos.
You can also have this as a theme for an adult party and enjoy sharing your trip and food, music, etc. from that place with your friends.
