We would not go back. The venue was gorgeous, and we did get to see some golf because we arrived relatively early, but by about noontime the crowds were too large to permit easy access to many of the spectator-favorite holes, and I would guess at least half the people in attendance, many of whom appeared to be college-age, had no interest in the golf at all and looked at the event as one big block party. This attitude is actually encouraged by the relatively low ticket prices with no limit to the number sold, the free-flowing beer, and the raucousness surrounding the 16th hole that this tournament is so famous for and which sometimes carries over to other holes.
Our no-interest-in-golf suspicion was actually confirmed, in a very minor way, in a conversation we had with a waitress at a local restaurant we went to right afterwards who saw the ticket that I had taken off of my shirt and set on the table. She said, "I have a friend who is going to that, and she doesn't know anything about golf."
We had originally planned/hoped to watch some on-course golf in the morning and then go over to the 16th hole and watch a few drives and the corresponding cheering or booing. Never happened. The 16th is completely surrounded with bleachers, and the number of spectators allowed in is limited to the number of seats. We saw long lines, and we didn't want to stand around waiting for people already in the stands to leave so that we might get a chance to enter. We could have been waiting all day. If we ever went to this tournament again, which we probably won't, we'd make a point of going to the 16th first thing in the morning and getting some seats even if it meant waiting an hour and a half or so for the first groups who teed off on hole #10 to make their way around to this hole.
We have been to other PGA tour events over the years, including the PGA Championship, The U.S. Open, The Memorial, the WGC at Firestone, and twice to The Players Championship. In all of those situations, the focus was the golf, and the fans were appropriately respectful. I wish that were more in evidence at the Phoenix Open.
