A good friend told me the best time to goto Pebble is the week before the concourse, it's when the course is in the best condition (aside from for tournaments), and both times I have gone on that weekend, the course has been immaculate. Also get to meet a lot of interesting people. One year I woke up, opened my lodge door, and saw Jay Leno in the room next to me, really cool guy.
I absolutely love Pebble, holes 11-14 feel a little underwhelming, but overall, still a huge fan of Pebble.
