Good questions. I am not opposed to the Central East region. I like that Central area, and based on the hotels you have listed in the thread at 4 and above in those two regions, I'd be happy with any of them...Cosmo, Bellagio, ceasars, PH, Paris, or Cromwell. I would probably start my bidding in Central West at 5 stars, then add Central east 5 stars. Then go to 4 stars across those two.
On the NYOP page, I didn't see that I could do 4.5 and above, just 4 or 5. there is a 4.5 express deal in Central west which I assume is Ceasars, but that costs even more at 297, than the 249 deal for a 5 star for my dates of 5/19-5/22.
I just got back from the Cosmo earlier this week. I am going to be in Vegas a few more times in the coming weeks, and I just booked Palazzo for April 2-5 with the PRICELINE EXPRESS deal at $163. I attempted to get it through NYOP, but was unsuccessful even at $155. I started at 110 and kept incrementing and adding regions until I hit $155 and was still unsuccessful. i just gave up and bought the express for $8 more. This is telling me that the NYOP acceptable offers are pretty close to the Express Deals price...or at least it was in my instance. Are you guys seeing this too? So if the epxress deal for the 5 start Central west is $249, I am guessing that's going to be my price if I want Cosmo or Bellagio.
