Oh yeah, I remember those. Back in the day (80's and 90's) those puppies were worn out as they were the best game in town for mapping out stays at Marriotts. As if an indication of future trends of cost management, as the company grew and the properties increased in numbers, the books became harder and harder to find at the properties.
Man, how did we ever schedule out of town trips (restaurants, activities, hotels) without the internet? It has become a blur, even though I know we did it. Thanks for the nostalgia.
