Hi, Maya from Wix Bookings here 
I think that on this usecase you don’t need the Wix Events app at all and can use only the Wix Bookings app.
You can setup a service from type class, with up to 5 participants, repeating every 30 min between 6-10 for 2 weeks. This way you’ll get the benefit of using the timetable we have in bookings.
Let me know if you have anymore questions.
