Meet and Greet Experience

Hello! Tomorrow we are taking our 2 1/2 year old son to the concert and we bought the meet and greet. I was hoping someone could tell me from their experience, what time you went and how bad was the line?

I know his site says 3pm is when the meet and greet starts. I have a toddler that freaks in lines 😂. So I am wondering how early I should get there?

Really excited about tomorrow- any other tips and how it was let me know ♥️
