3. BYO. If your allergies are severe and plentiful, bring your own lotions, creams, oils, nail polish--whatever you need to in order to ensure that you will have a relaxing, allergy-free experience. I did this recently in Bermuda at the Mandarin Oriental's Spa at Elbow Beach, where they were happy to use my small bottles of fragrance-free oil and lotion.

4. Even the nonallergic can get allergic. At the wonderful Standard Hotel in South Beach, my friend was offered a free herbal bath. She become a human teapot, soaking in a tub of hot water as staff members added a human-size tea bag full of herbal goodies and then let her steep. About five minutes into the bath, my friend started to turn pink. She thought maybe the water was too warm. Later, she had wine with dinner and that's what did it: herbs + liquor = red, blotchy, and itchy all-over allergic reactions. We alerted the staff, who exclaimed, "This never happens!" But, dear ones, it does. Just because you aren't an allergic girl doesn't mean you can't get allergic.
