Historic Bedford Springs Hotel to Reopen in May

BEDFORD, Pa. — The historic Bedford Springs Hotel is set to reopen on Memorial Day after undergoing nearly two years of renovations costing $100 million.

Owners are installing modern conveniences such as flat-screen TVs, wireless Internet access and a state-of-the-art business center, while preserving the original character of the facility's 10 buildings. "It will be an unusual blend of the glories of days gone by and ultra-modern conveniences," said Mr. Winston, general manager. "That's the challenge — when the property was constructed, the requirements of electricity and heating/ventilation were very different. There was no air conditioning."

Dr. John Anderson bought the property in 1796 after discovering natural mineral springs on the grounds. He built bath houses for his patients and the resort's popularity soared in the 1800s.

The Springs served as the summer White House for James Buchanan, and other presidents also stayed there. Owners say rooms of the 216-room will start at $250 a night. They hope to gamer a 4.5- to 5-diamond rating from the American Automobile Association.

What is NOT mentioned as new conveniences？

A．Videoconference facilities.

B．Flat-screen TV.

C．Business center.

D．Wireless Internet access.
