Boulevard Pool, The Cosmopolitan
Consider this pool scene the icing on a layer cake of Vegas aqua-decadence. Partly because it’s hovering over the Strip, but mostly because it’s fair game for the Cosmo’s new all-you-can-drink champagne program. You heard us: all day, all casino bars will be pouring as much bubbly as you can imbibe. The real winner: your cannonball.
