Why pay for a license guide when you can get a more genuine local experience from a local for free ?
Experience the local culture when you travel abroad with your local friends by using points instead of paying money.
And when another foreign friend visits you in the future, you can receive/collect your points again from your friend in Potluck Stay.
Cost: high VS free
Benefit: Convenience VS Genuine local culture experience
Relationship: Service provider and Customer Relationship VS Friendship
Making Friends: Long-lasting friendship with your guide? You're kidding! VS Meeting someone who is willing to help you around? That's friend!
Other Options: No other than sightseeing VS Participating in hobbies, cultural performance, and attending parties with friends, etc.
