I only charge for a non-refundable 1/2 deposit for major holidays and bookings that are made 2+ months in advance. If it is an emergency, I am generally flexible and can fit you in on certain days. If you cancel as I'm showing up to your house, I will require full payment of time you were going to be away. If you need to add time, just a standard pay for each day is required immediately through Venmo, Paypal or upon arrival home.
