Calendar/booking - one staff member only one time slot - two options

Can I check a possible issue with you all - on the booking system/calendar.

I have a client with one member of ‘staff’ and one ‘workplace’ - but they offer multiple options in the same fixed time frame. Ie the staff member can give more than one service.

For example:

Option 1 is a all day hire of the workplace.
Option 2 is 2 hour slots of the workplace,

I have added these as a ‘class’ as appointments will not let me assign 2 hour slots.

My question is if a 'clien’t books an all-day session - with the calendar automatically block out the clashing 2 hour slots and Vs if the ‘client’ books an two hour slot, will the calendar cancal the availalabity of an all day hire?

Thanks
