Could I sue them or something? I am not white though?

So I went to a motel and asked if I could stay for a longer period time like 30 days. They kept saying some workers and people reserved the rooms already and I couldn’t stay longer. I was there for 4 days. After a couple days i went to look around and saw some empty rooms and cars right by the doors. Could they get in trouble for this?
