Can't answer most of the questions because I live in the Atlanta area and the times I've gone I've either gotten tickets through the lottery or gone as part of a corporate sales event.

Food at the Masters is really cheap. $2 sandwiches, $3 beers, etc. The merchandise is not. But you get a hat or shirt with the masters logo, so that's something.

Holes - I enjoy sitting across the lake on 16 (between 6 and 16). Like the grandstands behind the 8th green. Really like sitting behind the tee box on 4 and watching them all get frustrated - the discussions are interesting.

Enjoy! It really is a magical place. Super clean and everyone is very friendly.
