Tom,
re: the Punchbowl and Preserve - I took my dad to Bandon (it was both of our first trips), we arrived Friday evening and went straight to Shortys and the Punchbowl. We did get out to Bandon Preserve on this trip, but Shortys had a few groups on it Friday night, when I went back Saturday and Sunday morning before my rounds it was empty. The Punchbowl had a little more traffic, and I thought it was a great way to hit some of the creative putts I would eschew in the rounds in favor of a reasonable putt (can't lose a match to my dad...).
For me, Shortys almost stole the show, even overshadowing some of the 'real' courses. Saturday morning I arrived just after sunrise and had the place to myself. It was the most fun I have ever had golfing. Kidd did a great job on these green complexes, particularly #4, and (I think) #6, #8 & #9. The practice was invaluable for learning shots that work all over the resort, but most important, it was fun. Did I mention I had fun?
The Punchbowl was also great. After Shortys, it seemed a little constrained having a 'course' marked on the Punchbowl, but as it fiulled up it was pretty apparent why they do that. At night, it seemed like a place for golfing revelry more than practice. As a pre-round warm up before PD, it was great practice and helped get my mind on the ground game.
regarding feet: I've run 100 miles, and I think of my feet as being pretty tough (if nothing else, I don't take any shit from them). Bandon did little to change that, but I did develop a nasty blister... My poor father was 4 up after 30 holes of a 36 hole day, but I beat him 4/6 holes to finish and tie the match. Endurance is a good golf quality too...
6 rounds: OM-3, PD-1, BD-1, BT-1.
