Bringing the family pet on vacation may seem appealing, but it can inflate costs dramatically. Airlines and other transit providers charge up to $200 one way for traveling with all but the biggest animals, while fees at hotels that allow animals can hit $100 a day. Once at the destination, you may be limited in choice of attractions, forcing you to make decisions based on restrictions rather than interests. Moreover, travel can be nerve-wracking for pets, and there's always the risk of the animal getting sick or wandering away. In other words, make alternate plans for your pet.
