Armed guards loyal to Colonel Muammar Gaddafi who have imprisoned the journalists in the 120-room hotel are still outside and the fear is the reporters will become hostages or human shields for desperate remnants of the old regime.
In the past few days, the chimes and surreal intercom voice that had summoned them to press briefings in the middle of the night have been replaced by artillery explosions and sniper fire.
Amid the marbled, chandelier-lit hotel, complete with a luxury spa, the journalists have been forced to retreat to the basement on several occasions or exist by candlelight during frequent power cuts. Some have found the doors to their rooms kicked in and their property rifled through.
They have tried to stay upbeat despite the surrounding battles and the undoubted frustration that they remain trapped while correspondents with the rebels appear to have unfettered access.
"For those worried about #Rixos This is not comfortable position but BBC CNN reuters AP fox sky china tv etc are all in good spirits," the BBC's Matthew Price tweeted yesterday.
From the beginning of the conflict the £500-a-night ($995) Rixos has proved a gilded cage for international correspondents, constantly under the eye of Gaddafi minders determined to manipulate the media. Journalists could leave only with official chaperones.
The sinister undercurrent was shown in March, when Eman al-Obeidi burst in on journalists eating breakfast to expose her story about being raped by Gaddafi loyalists. Previously placid hotel staff suddenly wrestled with Obeidi, beating journalists back.
Some, using the excuse of visiting the local convenience store or simply through grim determination, have managed to slip the net briefly but rumours abounded that taxi drivers were under strict instructions to return them to the authorities. Over the months the grip has become vice-like.
But as the rebels surged into Tripoli, the surreal facade of the hotel shattered. Price described how the families of government officials and then officials began to disappear. Then the translators and state-television employees left. The minders who did remain started carrying guns.
Moussa Ibrahim, the Libyan Information Minister, reappeared to give a press conference but soon vanished along with the other officials. Trucks loaded with anti-aircraft machine-guns appeared outside the Rixos and loyalist snipers were posted in the area.
As the hotel was rocked with explosions, the journalists donned body armour, lit candles and listened to the gunfire in the dark. The few kitchen staff that remained found food for them.
"We all want to go downtown to report on what's happening but it's not safe," said Reuters correspondent Missy Ryan on Monday.
"I wouldn't say we're hostages but nobody is going out."
Yesterday, as the BBC said it was doing everything it could to ensure the safety of its staff, the battle continued to rage around the Rixos as the reporters tried to access the internet and conserve the power on their satellite phones - their one lifeline to the outside world.
