I kind of hate to think of how many hours per day day I spend gambling in Vegas. Usually I start around 10:30 am and quit around 10:30 pm with breaks for lunch and dinner. We always go for over a week so an occasional night is for a show or two. I can also subtract the time spent walking to various casinos, washrooms, and getting fresh air. I'm not much of a shopper anymore. For me it likely averages out to nine hours per day.
