Question on concerts. This is my first Ado concert/concert in general

I do know her no photo and videos when performing rule

Are earplugs recommended at concerts?

Are buying parking passes an absolutely need to do?

What’s the average length of an Ado concert?

How early should you arrive to one of these events?

Are those light sticks provided or do you have to bring your own to her concerts?

Any tips/suggestions for me plz say them 👍
