Perhaps out of the question, but if your wife likes walking a nice piece of land, and Dormie Club allows it...
My wife and I both have very fond memories of her walking with me while I played -- with a couple of pensioners at the Old Course and, a couple of days later, at North Berwick, where I played alone.
My memories might be marginally fonder than hers, but only marginally. She won't soon forget the kindness of one of my Old Course companions, who, on a very cold, windy, rainy day, dug into his golf bag to outfit her properly -- with some sort of hooded rain shirt and some woolly mitts.
