Since most have 'homes' close to Fast Travel locations, I don't see why it's that much more time consuming to FT there, fire them (or they'll FT there themselves now, just not for me

), then FT back to get them. Especially when you have to walk the strip, enter the 38, take the elevator etc. Boone goes back to the Dino, Raul has his own FT shack location, Veronica the 188, ED-E back to that house in Primm, and so on.....but it is kinda cool to have them all hanging out in one spot for kicks.
Also, if you go against House, I think you eventually lose the option to even send them to the 38. But maybe there's a way around that even, never tried. Seems like there's a way around almost everything, either by design or glitch. lol
