I am currently covered in flea bites from staying in a room that a dog had previously occupied. This has changed my entire perspective on dog-friendly hotels and I will go out of my way to not stay at one again. Pets can impact people in hotels even after they have gone – from fleas, to smells, to allergy-inducing dander. Children do not have this kind of impact on those who stay in a room after then (and no, I am not a parent) If hotels are going to have pet rooms, don’t put people without pets in them.
