I think that might be after we get up there but I'm not sure.
Could we argue that Rand is a wealthy entrepreneur "investing" his funds in Breko and that the group consists of Rand's advisors and clients and bodyguards? Maybe even going with Gallador's tactic of posing as a syndicate member of some sort. If it helps, he can claim to be seeking for future business ventures with Merik and his casino.
Rand will go ahead and do that, then. With a wave of his hand and few simple words suggesting that Breko needs his staff with him, Rand forces security to accept the large group by influencing him with the Force.
Drop the point into it and avoid wasting time. With the Bureau here, we want to get up there quickly.
Should our pilots depart at this point?
They have to be here for someone/something else, but if we go investigating, we run the risk of them discovering our presence here. Also, if we head to the starport, we'll be hanging around for them to find us and left out of whatever goes on upstairs.
Then again, if we go upstairs, harder for us to leave if something goes wrong or the action starts too early, I'd assume.
