First, maybe talking with your insurance provider can help, or maybe talk to the person manning the front desk of your hotel. I'm sure if needed you should be able to visit an ER type doctor's office. When you have it sorted out please have your wife always, always take an inhaler with her. I have had asthma since early childhood. I understand about the cold and damp air, it does affect the breathing. If she is having trouble breathing please see someone as soon as possible.
But, also, steam seemed to help my asthma symptons in a pinch.
