The Station has a number of different stealth/low profile ships, the smallest of which seats a single individual and the largest of which can comfortably accommodate fifteen (meaning you can cram about twenty-five into that bad boy if push comes to shove and you don't care about wearing a seatbelt). There's a few mid-size ships that fall between those two extremes as well.

As for how many you can actually take-- well, that's up to you all now isn't it? :)
