Hilton Times Square | Orlando | Chicago

According to published reports, the number of allergy sufferers is increasing: Freak weather patterns have only made a bad situation worse. But now, watery-eyed, runny-nosed travelers can breathe easier. Several hotel chains (Doubletree, Fairmont, Hilton and Hyatt among them) feel your pain and are out to do more than simply offer extra tissues. Hypoallergenic rooms — the new norm, you might say — are available at select properties. And expect more to come online as the trend gains traction. Protocol includes carpet and upholstery sanitation; power-cleaning of heating, ventilation and air-conditioning units; installing tea-tree-oil cartridges to act as an ongoing natural disinfectant; and offering three-speed, adjustable, Class II medical-grade air purifiers in the rooms. Additionally, a special coating that repels pollen, germs and mold is applied to all surfaces, while pillows and mattresses are encased in hypoallergenic material. Specific “green” cleaning agents are used in housekeeping service and, at some properties, fragrance-free bath products are available upon request. Hypoallergenic rooms typically cost about $30 more per night and are located in some of the country’s most desirable spots. Here are some of our faves:
