Customer adding additional info after booking?

Of course my first Rover booking and a few things are off. The customer has to fly out of town for an emergency. It stated Drop In for 2 dogs. She did not have time for a Meet and Greet so she gave me the info in a message. After booking she stated one dog could not walk as far as the other and where to find their leashes. When we first messaged, I asked her if there were any certain times needed and if there were any special instructions. She stated no. My first visit will have to be after I get off work from my PT job tonight. I do not feel comfortable walking after dark in a strange neighborhood. I do not mind walking them in the early AM or around 5ish. Can I get in trouble with Rover if I do not walk them tonight if she did not sign up for Walks? ps..... she informed that there is a cat too but not booked.
