Max led the group to the rooms he had picked for them, halfway up the Cruise Ship area, and well away from where the others were staying, just in case there was an incident or the negotiations fell through at the Black Wolf end.
The last thing that he wanted was for one of their visitors from the Alliance to be injured or killed. It would ruin not only their reputation but the reputations of all humans in the eyes of the Alliance arbiters, even if the Illithid spoke on their behalf.
Some barriers could be deployed all over the ship to stop a violent rampage, but even one casualty was too many at this point, and it was making even the most basic of hospitality seem stressful to Max. Mercenaries, like the Reavers themselves, viewed it as rude and a sign of distrust to ask them to leave their sidearms behind, so he couldn't even do that much to ensure the safety of his guests.
