PH2 is my second favorite US course, and we will go back again despite the cost. But I am not a fan of PH4 or PH8 so the Doak course will make the two night minimum to play No 2 tolerably expensive.
As to vibe, even as an older couple, Pinehurst can seem a bit stuffy to us which besides the golf is why MP/PN is our annual hangout. One of the things that we admire about Bandon in addition to the golf is that even though it might be the ultimate guys trip destination, my wife has always felt comfortable and welcome even though her bar tab is pretty modest. Other than the golf, she did not particularly care for Streamsong—did not feel authentic even as a guys trip destination.
