Was out there today.
Changes on pretty much every hole, some quite minor, some (4, 13-14) are almost totally new. It's fine, but even the new holes don't feel especially different. This course has always been pretty boring front nine with a pretty good back nine, 15-18 being especially fun both for tournament watching and just playing as the average hack.
Have to agree with Shack that if they took the time to renovate essentially every hole, it's a shame that 1-9 are still pretty forgettable.
The bunker sand is atrocious and I heard several people comment on how bright and weird it looked. Very unusual out here and it won't last, which is maybe the saving grace.
