Very good suggestion with the plastic and the Cooler. I use the platic bag trick when it's excessively humid (summer) or dry (forced air heat in winter) works like a charm. Cooler is great for excessive heat as is an empty unused refrig. Basement is good for summer as it's cooler but beware many basements have excess humidity.
I left my stix for 2 months when I was in prison (Warrant Officer Basic Army School
) and it was AOK. You'll be fine cigars are pretty resilliant IMHO.
