Sorry for the late response to your PM, I've been on vacation.
I went to the PGA in 2002. Getting to the course is a nightmare. I don't know where you are staying, or if your pal has better accomodations, but for the rest of us you have to drive to Canterbury Park to park and get picked up by the shuttles. Then you ride the shuttles for 20-25 minutes until you get to the dropoff at the course. Then you have to walk quite a bit to the entrance where they frisk you etc.
Just getting in is quite the process so leave yourself plenty of time. And you really can't arrive early enough. Sunday of the PGA my friend and I were at the shuttles by 6:30AM and there was still a line.
The plusses are that if you are coming from the North, they have gotten rid of all the stoplights that were there in 2002. So getting to Canterbury should speed up quite a bit. Also, the shuttles are almost running constantly so there is little just waiting around.
To the course, I didn't mind the grandstands behind 9 and 18. You can see both greens. They do fill up.
The best spot that I liked was the top of the grandstand behind 7 I believe. It's a par 5 and most all the pros were going for it in 2. The grandstand is situated that the shot is coming right at you and you can see it the entire way. Being on the top of the grandstand, you can stand up and behind you you can watch the entire Par 3 8th hole. They tee off right behind the grandstand and the green is easily visible. I think there is one other hole you can keep an eye on while you are there. But I'm just trying to remember at this point.
Number 16 is a great hole to sit down just past the dogleg and watch. A very scary hole for most everyone in the field. Lots of risk/reward. Lots of pond balls or creek balls too. From the dogleg you can see the tee shot and the action on the green.
There are lots of hills so be prepared. Start doing some interval training this week.
Trying to follow Tiger at a major at this venue is a joke. Every day, in 2002, the throng following him was at least 8 deep. And with that many people moving, you can't get to where Tiger's next shot will be before he hits it. By the time you can get that 300 down the fairway, and get situated, he's already on the move.
What I would do differently is to try to get to the landing zone of the hole, not the teebox. With so many treed doglegs out there, you won't be able to see him swing from the landing zone. But if you are there and against the rope, you should be able to see his next swing, and the action on the green without moving. Then move to the next landing zone.
Watching shots from the teebox just so you can shout "Get in the hole" or "You da man" and get heard on TV is really only for idiots anyway. The way the tee boxes are raised, really only about the 20 people against the ropes can see anyone tee off.
And they got there at 7AM.
I would get a top-down map of the course and plan strategy on how to get from landing zone to landing zone once I got there.
If I was to do it again, I would get to 16 early on Thurs and Fri and spend more time there.
I hope this helps. If you have any more questions, just ask!
