Well it depends on what you like better!
If your a Criss Angel fan, like me, The Luxor is going to be THE place to stay! I love it there really because its all Criss Angel and its THE place to be if you want to see him. It has Criss Angel EVERYWHERE and when I went, the Believe show was SO amazing, especially since my room was NOT far of a walk at all from the show. It took maybe 3 min, but only because we walked so fast because we were so excited. Its VERY nice there, but last time I was there, november, their pool stunk SO bad. But if your a criss fan, STAY THERE! but it your not a fan of his, its not worth it, im sorry to say.
But if your not a fan of criss, stay in the Palms! Because the Palms is very nice, but does not have any Criss Angel. and its VERY nice there (but so is the luxor). But I bet it has a better pool
