I am new so need some help please. I run a driving school and want to be able to offer the calendar as a booking system BUT I need to run either 1 hour or 2 hour lessons. This is in essence easy enough to setup for 1 hour blocks, BUT I need 30 minutes between each lesson for travel to the next client unless they book a 2 hour slot. Then the 30 minutes is not required. So if I had a 2 hour calendar and a 1 hour calendar it takes away the problem BUT then if someone books a two hour slot it wont take away the slot on the 1 hour calendar and vice versa. I am a solo driving instructor so can not add a driver as a resource for each calendar and using myself as a resource produces a conflict error. Is there anyway to work this?
