Visa overstay - silence day

Hey guys, I have my visa on arrival that will expire on the 17th this month, silence day it’s on the 19th and I heard it’s amazing and I should see it if possible.

Do you think there’s gonna be any issues if I overstay my visa for three days? Leaving on the 20th right after silence day?

Anyone did this? I know it’s a fee you have to pay, which I’m ok with I guess, but should I expect anything else?
