Question about a second project

Hello, I am planning a second project with your theme. For this I have two important questions:
Round trips: Is it possible to insert maps about the course of the round trip?
Day tours: For some day tours an out and back transfer has to be added. Can this be set on a km basis? So Hotel A to Park B distance 88 km a 1.12 EUR per KM = 98,56 EUR. And Hotel B to Park B 22 km a 1.12 = 49.28 EUR. Or is it intended that fixed rates are optionally calculated in the booking process? But even there a selection from Maps is required.
Thank you for any information on this.
Jens
