Damon Hathaway knocked it out the park with that great information.
There's the JW Marriott, Fairfield Inn and Suites, Spring Hill Suites, and Courtyard by Mariott right across the street. The regular Mariott and Westin are a short walk down Washington Street, and the Holiday Inn, Holiday Inn Express, and Staybridge Suites are a little bit down West Street by Lucas Oil Stadium. There's also the Residence Inn and and Courtyard by Mariott near New York St and Senate Ave, by the canal, and it makes for a nice little canal walk to the museum, since its also along the canal further down.
Also consider the Conrad... if you want to walk around the Circle area.
Holiday Inn 515 s.west st and the Marriott are the two closest
