Jeff's comments seems fairly accurate in the context of all golfers, not just the well-heeled traveling golfer where a trip to Bandon is a mere dip into the proverbial petty-cash pouch.
Over the years, I've bumped into countless golfers on the public links, workplace, social gatherings, etc...and most have never heard of Bandon much less been there. I only met one person who went there and for him it was a one-and-done bucket-list buddy trip. I've also known and played with several other friends who were regular golfers and have far deeper pockets than me... but are perfectly content staying home and playing DS 3 courses as Tom alluded to in another thread.
P.S. I'm glad to hear there are plentiful repeat visitors to keep Bandon tee sheets packed, but it certainly represents a tiny slice of the golfing population.
Well, yeah, but by that standard every course out there is a one and done, and most are not worth paying up for even once.
Anthony's question was what courses we, on the DG, consider a one and done. Bandon isn't going to be that for very many here, as he said in the OP, although I suspect many would have one course or another that they'd skip there, in favor of the others.
I will answer the question by saying which famous courses I checked off many years ago, and have never felt compelled to go back to, nor to show any of my associates or interns around. It's a partial list:
Turnberry [although I should go back to see the recent changes]
Royal Birkdale
Wentworth [if people are even interested in it]
Aronimink [too many better things around there]
Oak Hill East [same caveat as Turnberry]
Congressional [completely changed now, I guess]
East Lake
Scioto
Medinah #3
Colonial
