If you haven't spent much time in the area before, unfortunately I'd tend to suspect molds. Allergies need exposure to develop a sensitivity to a particular allergen - I had three or four good winters in Florida before I became just as allergic to cedar pollen as I am to ragweed, sigh (as in, if I don't get the shots, I'm literally very close to incapacitated for the whole season). Still, while removing the source is always best, mold allergies are just as treatable as pollen. PM me if you want the name of my allergist in Daytona.
