Is it really crowded on sundays?

Yes alot of people in there. I was surprised myself

Thank you for your question. As one of the most popular casinos in the country - we are second in the state of California in attendance - we do attract quite the crowd. But good news! We are expanding to meet the incredible demand for our product: SanManuel.com/comingsoon. See you again soon at SoCal’s No. 1 casino! -San Manuel Casino

Yes

San Manuel is the most crowded around the first of the month when people get their SSI check etc. Then it kinda slows down . But always crowded on Friday and Saturday
