I'd not advise opening a bank account until he's sure he want to stay. How old is yer Dad? What's he like to do? Many single retirees enjoy a robust nightlife. Some just a quiet peaceful scene, with the ability to get out and eat at some nice restaurants. Does he want close to the beach, close to other expats? If we know what lifestyle he'll enjoy most, we can be more helpful in guiding you to the best spots. If living near a beach isn't high on the list, Chiang Mai offers a nice mix of entertainment venue's, and a lively expats community. Hua Hin is a slower, beach side, community with many older retirees. Jomtien is essentially a bedroom community, just South, and next door, to the sometimes wild and notorious Pattaya. If big city living is desired, Bangkok is terrific. If it's strictly peace and quiet he's after, then the Isan region offers many choices. Then there's Island living, several nice ones to consider. Best wishes for a
