Do you still have to make an appointment to enter the dispensary in North Aurora or can you walk in?

You can make an appointment but, from time to time, they allow walk-ins. They don't always post their spuratic walk-in times on their site.

I took my bf there and he didn't need an appointment time for recreation...

Yes

Yes you need an appointment

I believe for recreational you do need an appointment. I'm not sure about medicinal
