CISSY HOUSTON SEEKING 'CLOSURE' BY REVISITING WHITNEY'S HOTEL ROOM

Whitney Houston's mother Cissy has unfinished business to attend to -- sources tell TMZ she's planning a pilgrimage BACK to the Beverly Hills hotel room where her daughter died ... all in an attempt to get some closure.

According to sources close to Cissy, she wants to go back to room 434 at the Beverly Hilton hotel and reestablish a spiritual connection with her daughter ... in order to come to terms with her sudden death.

We're told Cissy plans to pray while she's there -- and just spend quiet, contemplative time in the space.

As one source put it -- Cissy "won’t be at peace until she gets closure."

It's unclear when Cissy plans to return to the hotel room -- but we're told the visit will be soon ... she's currently planning out the logistics.

WHITNEY HOUSTON FAMILY STRIPS HOTEL ROOM TO THWART LOOTERS

 Don't count on finding a scrap of Whitney Houston death room memorabilia -- sources tell TMZ, the singer's family has meticulously stripped the hotel room where Whitney died to preempt would-be looters.

According to sources, the family has removed nearly everything from room 434 at the Beverly Hilton hotel that hasn't been bolted down -- including bed sheets, towels ... even bits of trash.

We're told the family is concerned about people trying to make a desperate buck off Whitney's death -- raiding the singer's hotel room and trying to sell relics of her passing ... whatever it might be.

It's unclear exactly what happened to the macabre souvenirs, but we're told it was all disposed of ... discreetly.

WHITNEY HOUSTON HOTEL DEATH ROOM ALREADY RE-OCCUPIED

It's only been 3 days since Whitney Houston died in room 434 at the Beverly Hilton hotel ... but TMZ has learned ... the room has already been RE-OCCUPIED.

A hotel reservations agent tells TMZ, room 434 is officially back in rotation -- and someone is staying in it right now.

According to the rep, the room has become a prize for the macabre-obsessed -- we're told the agents are getting flooded with requests for the death room.

But don't count on getting in there any time soon ... we're told the room -- which rents for no less than $375/night -- is booked for the "foreseeable future."  The rep wouldn't give the next available date.

Update
The Beverly Hilton's publicist is now saying Whitney's room is not available yet -- which is a different story than a reservations agent and the Executive assistant to the manager told us. They both said the room is being rented out and is currently occupied.
