FOR JEWISH BOYS WHO HAVE CONSIDERED THE WESTIN WHEN THE OMNI IS SO CHEAP - that'll be the title of my home movies of Pittsburgh (if I had taken them)
Like I mentioned before, I've always loved Omni Hotels.  Did you sign up for their Select Guest program?  The regular perks are even nice.
*And if you want a really nice splurge, I highly recommend the Omni Berkshire Place on the East Side.  Very, very nice.  And if no one happens to be in them at the time, sometimes they'll give you a peek at the full-floor suites.  The Rodgers & Hammerstein suite is truly 
luxe.
**And some of their weekend rates in the summer and winter (January) are pretty comparable with some of the midtown mainstays.
