Bring extra drinking water. Having a large bottle of water on an airplane trip always proves useful. Even when the flight attendants are diligent in serving water, they give you very small cups.

At a Vacation Spot

Consider the season. Just as weather varies widely around the globe, so do regional allergy seasons. Check average pollen counts for your destination before booking your trip.

See the medical sights. Make sure you know where the closest emergency medical facility is located--just in case.

Pick the right lodging. You're probably better off at a modern, sterile hotel than a cozy (and probably allergen heavy) bed-and-breakfast or inn. You also may do better staying in a hotel rather than in a friend or relative's home. Some hotels, for example, even have special allergy-free rooms, or allergy packs, including face masks, special pillows, and mattress covers.

Pick the right destination. Exploring damp, musty caves, or touring old, historic houses probably aren't the best vacations for you. How about the beach or the mountains, where the air is clearer? Or a cruise on the pollen-free open seas?

Use housekeeping services. Many hotels ask if they can change the sheets every other day or when you leave. That may be fine for most people, but someone with allergies needs clean sheets daily.
