With some tips from other site, I was able to book the Cosmopolitan for $53 a night via Hotwire from 6/30-7/3. That week and some other days seem to be available in the $50-60 range. Basically, you're looking for the pet friendly 5-Star "The Strip - South area hotel". My understanding is that only could be the Cosmo. Not a fan of doing these blind hotel deals and being nonrefundable, but can't beat the rate.
