Lauryn Mark is also representing the Australian team in shooting, but husband Russell says officials have banned them from staying in the same accommodation.
"I've been trying to get a resolution on this for several months," Mark told ABC Radio.
"You'd be pretty naive to think there aren't other athletes in other females' or males' rooms at the Olympic Games."
Mark has been told to share a room with fellow men's shooter Michael Diamond.
But the six-time Olympian says he wants to maintain his usual routine ahead of the trap shooting competition in London.
"I just want to keep the same normal routine that I keep in every other competition that I compete in all over the world, and I guess so does Lauryn," he said.
"I wouldn't have thought this was going to be the issue that it has become because at the Commonwealth Games, before I was married to Lauryn, they let us room together.
"That didn't seem to be an issue in 2002."
Mark says that despite the request being investigated by a number of agencies, a final resolution is yet to be announced.
"Everyone's blaming everyone else now," he said.
"The Australian Shooting Association are blaming the Australian Olympic Committee. And the Australian Olympic Committee are saying we don't have a problem with it if the Shooting Association can find you a room.
"I mean we put a man on the moon in 1969. Finding a room in the Olympic village can't be that difficult, surely."
The double-trap gold medallist at the 1996 Atlanta Games recently spoke out in support of athletes using sleeping tablets, after Mark himself admitted to using Temazepam in competition.
"I don't want to be made a scapegoat because I'm publicly saying I'm using them and I know other people are," Mark said.
"Don't make us out to be criminals."
And the 48-year-old says he is keen for his sleeping arrangement in London to be confirmed.
"I was told on Wednesday morning at 9:00am that my room-mate would be Michael Diamond," Mark said.
"Nothing against Michael ... I've roomed with him before but he doesn't wear a pink nightie the same way that Lauryn wears it.
"And he's not as cuddly and he doesn't shave enough and I've had enough of him."
