air gap

Hi, we are about to install a granite countertop and I have to make some immediate decisions about what holes to have cut into the granite. We just bought a new sink and gardbage disposal, and there is an existing dishwasher to the right of the sink (It's all on a center island) Our previous sink was a drop in on a tile countertop, but this one will need to be an undermount for the granite slab. We used to have an "air gap" on the sink, which sometimes released water, but I heard that with a granite slab you don't want to install an air gap becuse the surface is level and water would spill onto the countertop from the air gap. Is this true? The suggestion was to get a plumber to curve the hose in a way that creates a 6 inch loop (?) that serves in place of an air gap installed onto the countertop. Please advise because I need to let the granite guys know whether or not to cut a hole. Also, does anything need to be cut out of the slap for the garbage disposal?
