Ads for the band's four-week run at the Hard Rock Hotel & Casino depicted a disheveled woman who appeared to be sexually assaulted beneath the "Welcome to Las Vegas" sign.
The artwork came to the attention of county commissioners after they temporarily renamed a street Paradise City Road in honor of the band's famous song.
Rape crisis groups decried the campaign, saying it glorified domestic violence and could re-traumatize victims.
The Hard Rock issued a statement saying it regrets that the campaign offended members of the community, and it started modifying the ads Friday.
