SJSU Admitted Spartan Day

I didn’t RSVP on time to Admitted Spartan Day, can I still attend? Will they actually check if you have RSVPed? I’ve attended another university’s admitted students day and they didn’t seem to check if you registered, I think you only benefitted in terms of a parking pass. I am willing to pay for parking but I really want to attend, at least go to the presentation for my major and most likely a housing tour.
