Andrew Hepburn, in his 1965 book Great Resorts of North America, says that the resort was built on a site called the old Ashburn Farm. Stephens used local timber, including walnut paneling from trees on the farm and cypress paneling from a nearby swamp, hauled to Irvington by oxcart. In the beginning, there were only 47 rooms. From the start, Stephens sought the best antiques for furnishing. Hepburn writes that one of the best early recipes at the resort was the breakfast dish Hangtown fry, made of local oysters and scrambled eggs. The resort had a number of yearly traditions including a Frostbite Regatta and Fourth of July fireworks. The poolside restaurant was known as the Bubble Club. The resort had an eagle theme; not only was an eagle on the Tides Inn logo but the hotel's 1976 golf course, designed by George Cobb and John LaFoy, was named the Golden Eagle. The golf course is surrounded by a 50 acre lake and is considered the only operational golf course in Lancaster County.
