Wow.. so the person rents the place, then later dumps the concept of bringing one dog despite the owner's no dogs policy. Owner finally caves and says OK. Then later yet, renter wants to bring TWO dogs... and two more guests too.
Then, at last minute, renter disputes the extra charge for the two extra guests... and it all falls apart.
Which it makes it even dumber that the owner would sabotage herself and start spewing stupidity.
