How old do you have to be to be by yourself on a Sunday?

There are no age restrictions on Sundays. As long as minors behave themselves they won't be escorted out of the mall by security.

I believe every day after 5pm minors have to be accompanied by an adult now

There is not a Sunday age restriction. Only Fridays and Saturdays after 5 p.m., when anyone under 18 must be with an adult.

Have no idea

18 yrs old or be with a parent

Really cannot answer that question about the mall on Sunday.I ride the bus,the bus doesn't run on Sunday,I've never been to the mall on Sunday.
