Best 1br suite with pullout couch

[NoRiverRats]

Wife is letting me go to Vegas for 10 days with the boys for WSOP, Woo-hoo!

One small detail, she wants to come for a four day weekend and wants to bring her girlfriend. She wants her girlfriend to stay with us(don't ask) but wants to ensure we have our own enclosed bedroom and the girlfriend can have a pull-out couch. I am done discussing(arguing) this with her and need your advice, which hotel has enclosed one bedroom suites with pull out couches.

Oh, and we need to stay at a decent place on the strip.

V has big rooms with pull-outs but they are all open concept.

Mandalay has great suites with enclosed bedrooms but no pull-out couches.

I am willing to pay $400-$450 a night but no more, after that we are looking at separate rooms.

Thanks all
