I can't believe there is no pet fee option. My guests are happy to pay the fee but get confused that it can't be paid at the time of booking. Consider this, it takes additional transactions to get the pet fee paid. The host has to request the pet fee through a payment request and the guest has to make another payment. How inefficient! VRBO has a pet fee option and it works great. What is the reluctance? I don't get it. Very frustrating.
