Depends on the allergies. I have allergies to molds, as well as flowers, etc. Going to a place with high humidity would aggravate the mold allergy and I'd still have the flowers to deal with.
Are you sure the problem IS allergies? Sometimes, in a dry area, you can simply be getting dust in your sinuses - it's not an allergy, just your body trying to remove the foreign dust by making you sneeze.
