residents are able to have one overnight guest per night and this is not limited per month. after having kids i generally travel one month in summer and one month in winter. (the first two measurements are open rate and click-through rate.) for example, if we are in a diner and hungry and we see a menu advertising the “burger special” we will think about it differently than if we had just left a restaurant after a particularly satisfying meal and saw the same “burger special” advertised on a billboard as we were driving home.
