While we may not think twice about asking for a nonsmoking hotel room, one far away from elevators or on a higher floor, have you thought about asking for one far away from the pool? Many hotel rooms are right above indoor pools, which may sound convenient and lovely, but they are actually the unhealthiest rooms in a hotel. As the pool's water evaporates, it turns into chlorine gas, which can rise up right into your room. This creates an unhealthy air environment for you and your family. So be sure to pick a room as far away from the pool as possible for the healthiest stay on the road.
