The shared two bedroom suite is a thing that started recently. The 4 of us in my recurrent class this summer were asked our opinion about making it a standard thing for all training events. I think there's a nice Hyatt House in the area or something like that (those things are generally much nicer than my tiny 450 sqf apartment in LA for what it's worth). We told them that it might be worth experimenting with for initial since it gives people a more social setting to study, but it was a definite "hell no" for recurrents. They seem to have listened. During all recurrent training you get your own hotel room. However, they do like feedback so if you feel like it took away from your experience, please let them know, seems like they just started trying it out.

I got my KCM badge while back home waiting for IOE, so I don't think you'll have it during training to jumpseat home. For what it's worth, my class only had 3 days off during training and they were spread out throughout, so it wasn't really worth it to go back
