Muliple day service with multiple attendees

Hi

I'm trying to set up MS booking to allow customers to book several two day events with a maximum of 5 attendees per event.

I'm really struggling to do such easy scenario.

The best solution that I found so far is to :

set the duration to 1D10h

set the defaut availability of the service to non bookable

create specfic availibility during two days time slot with the option "when staff are free"

create 5 fake staff accounts (as it was suggested in others posts.)

Assign this 5 staffs to the service with the option " assign any of the selected staff" activated.

set the staff avilability to 8am to 5 pm

set the business hours availibilyt to 00:00 yo 23:59

It seems like a very complex workaroung for such simple scenario and in the end it's not perfect as it create several training sessions per customer wheres the option max attendees=5 is set.

What am I doing wrong?

Thank you in advance for your support
