Please help.....

My parents and I will go to Las Vegas this Feb. I booked Palazzo bella already--very pricy, I must say-- 720 fts with 2 queen beds, TV everywhere in the suites. (My parents aint big fan of Plasma TV though, they are v old fashion )
However, I got a coupon last night. It is Wynn, with the coupon code I can save about 600 dollar (for 5 night in total). It is standard resort room (640 fts) with 2 double beds. No living room though.

I have never stayed in Wynn or Palazzo before. Palazzo looks so beautiful and it's brand new. Wynn is new as well and we can do a lot with that 600 dollars ! I am not sure double bed comfy enough for my parents though, they are very picky.

Which is better option for us? Wynn or Palazzo?

Thanks in advance for any suggestion!
