Ok, I'm confused as hell here. My friend says that you cans send companions back to the Lucky 38 instead of back to their homes if you have the Penthouse, yet even though I have the Penthouse I can't send Boone, EDE or Cass back to the Lucky 38.

Is there something you have to do first, or is it just bugged?

It's bugged by the sounds of it. It should come up as a dialogue option when you tell them "it's time to part ways".

Have you gone inside the penthouse yourself? I had that issue in one of my games too, try going inside and hanging out in the penthouse. I think you might also have to do a certain amount of stuff for house or kill him at least. But once your character is able to use the penthouse, you should be able to send companions there as well. :confused:

It's not the penthouse man, its the presidential suite.
Sounds bugged though, when you choose to dismiss a companion it should just come up as an option..

Have you actually been inside your presidential suite?
I don't know because I always go in there and upgrade as soon as I can, but, maybe you have to at least go in before you can send your friends there?
