DETROIT -- Past guests include Elvis Presley, Henry Kissinger and Bob Hope. Danny DeVito and Jack Nicholson also stayed there while shooting the 1992 movie, "Hoffa." But the heyday of the 41-year-old Hotel Pontchartrain has long since passed.

Decreased bookings, lack of a tie-in with a major hotel chain and neglect have hurt the property in recent years. Now, officials are hoping a $12 million overhaul will help restore the hotel's luster.

The 25-story hotel will get a makeover for existing rooms and facilities, along with 54 new suites.The renovations are expected to be completed by the end of the year.

Shubh Hotels Detroit LLC, a partnership based in Boca Raton, Fla., bought the hotel last year, but only recently released details of the upgrades as well as its new name: the Sheraton Pontchartrain Hotel Detroit.
