Hello.
1) You can define the comma separated emails (or separated by 😉 in the field “to” or if you have activated sending a copy of emails in these fields at the Booking > Settings > Emails page.
For example:
email1@server.com;othet-email@gmail.com
If it’s will not work, then use this
email1@server.com,othet-email@gmail.com
2) In the Booking Calendar MultiUser version possible that each registered WordPress user (your owner) have own individual independent booking admin panel, and can see and manage only own booking resources and some other settings (other owners will not see the bookings from this owner, they can see only own bookings). Please check more here (at bottom of the page) https://wpbookingcalendar.com/overview/
Also each owner (user) will receive the emails about the bookings of their own service(s) or property (booking resource(s)) and can approve or decline them. Please note, that each owner WordPress user) will have different individual calendar(s) with booking forms in the separate pages. Please retest it in the live demo.
