With some of us reaching ever higher occupancy rates, I believe hosts such as myself are always looking for alternative ways to increase our income.
I see Airbnb experiences as a good way to do this. I rent an entire apartment and many times, guests ask about activities to do in the region, or recommendations for good restaurants, etc.
An option would be that we, as hosts, could recommend specific experiences (and potentially give a coupon or a referral code) and get a commission if they booked. I think this would be a win for everybody involved because:
1) The host of the experience would get more clients, hence earning more money.
2) The host of the apartment would earn additional income
3) Airbnb could earn extra revenue since potentially there would be more bookings via airbnb experiences and furthermore, hosts could push experiences even to guests that come to their properties via alternative platforms such as booking.com, expedia or tripadvisor.
