Less than 48 hours later -- with a cause of death still unknown -- the tour bus itinerary for Hollywood's Dearly Departed, the Tragical History Tour was altered to include Whitney Houston's death site.

We didn't add it yesterday because there was a lot of madness at the hotel, Scott Michaels, owner and founder of seven-year-old Dearly Departed, told The Los Angeles Times Monday. But this is what we do. And it's not far off our current route.

The 2.5-hour tour is an escorted journey through death, murder and scandal in Los Angeles in the cool comfort of the luxurious Dearly Departed Tomb Buggy.

It now passes by the Beverly Hilton hotel on Wilshire Boulevard as a guide discusses the circumstances surrounding the death of the departed superstar. The guide also ruminates on questions that remain unanswered and the possible cause of death.

Michaels said the hotel in Beverly Hills is not far from Bugsy Siegel's place. And Ronni Chasen was right there too.

When the 911 call becomes available, we'll use that, he added, saying that when people hear audio it makes them realize that these are genuine individuals.

The tour costs $40 per adult and heads out five times daily, depending on demand. It's constantly changing to add new additions like Elizabeth Taylor and Michael Jackson.

To some people, there's just no defending what his company does, Michaels told the Times. But we're not jumping on any bandwagon. This is what we do.

Room 434, where the incident happened, is reportedly back in rotation at the Beverly Hilton and is already re-occupied. TMZ reports that the room has become a prize for the macabre-obsessed and that agents are getting flooded with requests for the death room. The celebrity gossip site claims the room -- which rents for no less than $375 a night -- is booked for the foreseeable future.

Born into greatness -- the daughter of gospel singer Cissy Houston, cousin of 1960s pop diva Dionne Warwick, and goddaughter of Aretha Franklin -- Houston began singing in church as a child. In her teens, she sang backup for Chaka Khan, Jermaine Jackson and others, in addition to modeling.

From the mid-1980s to the late 1990s, she was one of the world's bestselling artists, dabbling in acting with films like The Bodyguard and Waiting to Exhale.

Houston ruled as pop music's queen until her majestic voice and regal image were tainted by drug use, erratic behavior, and a tumultuous marriage to singer Bobby Brown.

The biggest devil is me. Houston told ABC's Diane Sawyer in an infamous 2002 interview with then-husband Brown by her side. I'm either my best friend or my worst enemy.

Houston's family issued a statement Sunday saying, We are devastated by the loss of our beloved Whitney. This is an unimaginable tragedy and we will miss her terribly. We appreciate the outpouring of love and support from her fans and friends.

Houston's funeral ceremony is expected to be held on Saturday in Newark, New Jersey. The official cause of death will not be known for another six to eight weeks pending toxicology results.
