Firstly check what type of ticket. Does it have access to grandstands or not. Basically you have two choices, find somewhere & stay there, probably around Amen Corner, then you get to see everyone but only once. Or walk with a group a few holes and then drop back to the next group. If you do choose to stay with one group it’s unlikely that you get close to the greens but you’ll see them on the fairways only.
Check your ticket for what you can’t take in, normally very restrictive, for even things like water.
Enjoy.
