And human children can have lice, ticks, pinworms, and bedbugs. Difference between humans and dogs is that most normal people pay for prevention for fleas and ticks. You cant prevent lice, ticks, pinworms, or bedbugs on humans. It is only treatable after the fact. And I am 100% sure that their are more people who stay at disney or other hotels that accept dogs that have had one of those ailments than the amount of untreated dogs at a hotel. As said before in this forum, most people who travel with their pets, take care of their pets.
Pet hair, well nothing I can say about that one. Brushing helps but if you have dogs, pet hair comes with the territory. And lets not even start talking about how a house with children doesnt smell. Both houses with dogs or with kids smell. Houses that have both have both smells. If you clean your house like a normal person, then the smell should be minimal on both sides. So please dont start with the children do not stink up a house. People without kids can smell it.
