Although this was directed at someone else, I'm going to put my two cents in.
Previously the models stayed at the "
Broke Straight Boys house" out west, and from what we saw of it in the BTS videos, it was a luxurious mansionesque place with lots of space, pool table, pool, bunk rooms for the boys, etc. Since shooting has moved to the east coast I'm ASSUMING (as I have no first-hand knowledge) that it is much more moderate in scope, with much less room -- a regular house instead of a sprawling mansion. So when multiple models are there they probably have to resort to air mattresses for sleeping accommodations for some of them, just as any normal person would in their own home. Nothing horrible, but not fancy or luxurious.
The pay comment I have no comments on as I don't have the slightest idea what the models get paid here or at other sites, and it's not my business so I don't want or need to know that.
Maybe the other studio Junior works for has fancier accommodations and pay better? I don't know, but that's my take on all that.
