@Robert8416 Can't answer your question BUT you could have one person from each couple as the host and co-host then their partner just share the password with them.
Hi @Robert8416, you can create a listing in your account (for example) and add all other people as co-hosts to your listing.
Airbnb rules allow you to invite up to 10 co-hosts per listing.
You will all be able to manage bookings and communicate with guests (depending on the permissions the listing owner has given to each specific co-host).
You can find more information and detailed instructions here:
