<p>Well, my daughter got through six weeks of auditions, traveling all over, without getting sick. Who knows if it made any difference, but after reading about the germs in hotel rooms, I bought disinfectant spray on the way to each new hotel, and sprayed everything - the door knobs, the faucets, the remote control,etc. Also took a tip from another parent and bought a travel humidifier (find it online) that uses a water bottle for the water supply. It really kept the air in the room moist - and I think makes tissues less susceptible to infection. Hope this helps someone.</p>
