Tickets for Centre Court

Hi everyone,

First time going to Wimbledon so unsure of how it all works but I have secured a ticket for the final day on Sunday to No. 1 court but obvs would love to get onto CC. I seen grounds open for ticket holders at 10 am so do I head to resell then or do I get there earlier and I access resell kiosk earlier say around 6 am? And then head out and come back when the matches start?
