I'll be in Vegas during EVO , but am I able to watch for free?

I just found out i’ll be in Vegas during EVO, but am I able to just watch the tourney?

On the site it says

Does that mean I have to know someone thats in the tourney just to watch, or is it free for everyone to watch?

Its free to watch. You don’t have to know anyone either.

Oh awesome, thank you.
