Meet me in St. Louis at this trio of tony hotels, where everything old is new again.

Built in 1922, closed in 1989, and reopened in 1999 after a $100 million renovation, the Chase Park Plaza has just received an additional $70 million in upgrades. Its endless amenities — from the brand-new convention facilities to the 15,000-square-foot fitness center to the five-theater cinema — make Chase Park ideal for business or pleasure. From $189.

St. Louis’ first style-centric boutique, the 78-suite WS occupies a rehabbed beaux-arts treasure, converting former offices into spacious digs with full kitchens. Two blocks from the convention center, WS’ large day spa and a sleek lobby lounge do their bits to soothe the show-weary. From $189. (314) 231-1100,

Adjacent to the convention hall, Marriott overhauled the ’20s-era Lennox Hotel, maintaining its marble stairways, vaulted ceilings, and brass elevator doors, while installing 21st-century technology. The resulting 165-room Renaissance St. Louis Suites sports gracious guest room touches like French doors separating bedroom from living area. From $189. (888) 225-6459,
