Congrats! I have been and no matter how much you build it up, you will not be disappointed.
We went Mon-Tues and were there before the gates open and got great parking spots.
For me, the players are secondary, it is all about the course and the experience.
Old timers in line all agreed on the following:
Walk the course backwards and you don't have to face the crowds following players off 1.
We did just that, found some players who started off 10, but walked Amen Corner virtually crowd free.
Along the way we decided where we wanted to sit and staked out 12. For us that was a good choice on day one as it gave us a first hand experience of why these guys have difficulty hitting that green.
we were shocked you could leave your chair / blanket etc in place unattended and come back to find it undisturbed.
After walking the course we bought our souvenirs, some one took it to the car and we headed to 12 or other holes.
Do see the whole course as you will be amazed by the contours, bumps, humps etc. #10 could literally be a down hill ski run.
This place is absolutely pristine and manicured like no other and I have been fortunate to attend US Opens and a Ryder Cup. Food is unbelievably minimally priced and clothes, hats, etc, what you might expect.
To say have fun is a gross understatement and guaranteed.
