Are there special hours for Easter weekend?

From websites and other sources from Salmon Run, no. But certain stores and vendors inside the mall may change their hours. If you're looking for a specific outlet to shop on those days, check their hours on the internet. Here's a link to regular hours for the bigger shops. https://www.shopsalmonrunmall.com/hours/

I'm from Canada and most stores are closed Good Friday and Easter Sunday 🙄

I'm not sure I was in the neighborhood for a weekend vacation
