So that $145/nt kept eluding me. Every time I checked, it would show $165/nt. I ultimately went to the Palazzo website and found that they were offering a deal for new members - book 3 nights and 1 is free. For 2/2-2/5 (3 nights), it came out to be $145/nt - not so coincidental I feel. Since this is a $145/nt lock for a room at Palazzo, I went for it. The resort fee of $39/nt is rough but it's a very nice hotel - so far so good.
Wanted to thank you guys very much for the help! I will certainly be linking through for all future activity on PRICELINE or HOTWIRE and will likely be back for for more guidance - thanks again and keep up the great work!
