You'll enjoy yourself tremendously and the advice you have received here is excellent. You will, indeed, be impressed by how hilly it is, and also how long. The chutes that many of the tee shots have to fly through (between the pines) are impressive. It is definitely a "big boy" golf course.
I would suggest a few stops for you: 1) the practice area. it's huge and if you're there early you'll see everyone out there, including the hangers on...the harmons, etc. 2) get your photo taken in front of the clubhouse, and 3) get a good look at the members having lunch outside their private area, don't be surprised to see Arnie having a sandwich with Jack or something similar.
Despite all of the animosity that so many in our society direct toward the ultra-wealthy, you'll be treated exceptionally well at Augusta National. You'll see member in their jackets amongst the regular folk and, not forgetting that these are incredibly high powered and rich people, they are friendly and helpful...willing to give directions, advice etc. The member who directs you to the 8th tee today may be having lunch with the President tomorrow..
I'll just quickly mention...the gift shop is reasonably priced...........the food is downright cheap ............ there is no running, you're expected to behave like a grown up at all times....you can leave your folding chair to go the john or grab a sandwich, and no one will bother it..........just an incredibly pleasant and memorable experience.
To me, it was like going to church.
