Do you charge per drop in visit or are multiple included in the price?

As you noticed, there are many interpretations of Rover's recommended guidelines. Each sitter&pet parent can customize what they need covered in the bookings.

A drop in charge is per visit. So, that would be $12 for one 30 minute visit. Two visits would be $24 (12 x 2). Like you,some sitters also offer house sitting and if your availability allows that, some sitters would not exceed the amount they charge if multiple daily visits needed (in your case $30) and may spend more time with the dog(s).

Agree with answers above but will add that the reason the drop ins are priced per drop in is due to the travel back and forth vs housesitting where you likely will just be at the house and won't have all the back and forth travel of a drop in.
