Bench seats always helps with that.
if you have 4 chairs with 2 fans and 2 empty, it looks 50% full.
If you have a section of bench that seats 4 people, and 2 people are on it, and spread out, it looks 75% full.
That is why I hate when people compare us to UCF by photos, the rigid structure of individual chairs shows empty seats more than benches.
