Mike,
Make sure you play all three before deciding to skip one on a future trip....
Although, I would make sure you play Bandon Dunes first, then Bandon Trails, then Pacific Dunes.... This way, it only gets better, and you won't feel that you should have played one of these last two rounds on Pacific Dunes or Bandon Trails, which, IMHO, are much better courses, appart from the views that a truly spectacular.
That being said, BD is not bad. I just prefered the two others by a fair margin....
Have a good trip.
