Step 1, get a copy of CBJN from the folks at bj21.com . Step 2, to quote Pro21, "You must do your own scouting." Multiple deck rules should be OK anywhere in Reno. CBJN will fill in the details. Pen tends to be highly dealer-dependent, so consider CBJN to be only a rough guide. And it's not good to be putting up posts along the lines of, "The Tangiers has the best penetration at double deck in the U.S." It might lead to the game disappearing tomorrow. Look around, and you might change your mind about single deck, at which pen is occasionally stupendous in Reno.
