It is much easier to enjoy the cars. Less people traffic, less real traffic getting in and out of the track. There are probably a lot of shops/events that aren't open or don't happen until Saturday and Sunday so it does feel slightly less festive. I feel like Sat & Sun are the true event days. Where the days before that are just all about the cars turning laps. This year there is a full "pre-event" weekened, my feeling is this is just more track time for all the cars. Formula 1 cars this year!
