Hotwire Hotel: Universal Studios hotels?

[LoneStar]

Mousesavers says you can sometimes get the Universal Studios hotels (like Portofino, Pacific Royal) on Hotwire.

But I can't recall seeing these hotels ever come up, and I certainly don't see them available for my potential travel days in early February. I am wondering if I should "hold out" to see if they eventually pop up, or give up on the idea of staying at a Universal hotel. There do seem to be some significant benefits to staying at a Universal-affiliated hotel while visiting Universal (your room key give you extra opportunities to skip ride lines), but the benefits are not worth paying retail for.
