This client is going to go on a two week tour offering two simultaneous appointments per location and most days will have two locations at a time. So in my mind, we need to combine appointments with events.
Here's how it might look -
Sunday - 10 am to 3 pm - 15 minute appointments available with two technicians for location A.
Monday - Nothing
Tuesday 3:30 to 6 pm - 15 minute appointments available with two technicians for each location B & C.
They never return to the same location but the location needs to be clear. Any help with how we might be able to leverage the existing plugins would be greatly appreciated.
