I went in September for a week - most amazing place on the planet!
Did the helicopter over the canyon and then landed in it for dinner. I did the sunset tour which the women seem to like!
Def agree with going to the club at Palms, amazing to be drinking so high up, bit scary when you look over the side though! Not sure it's clever having people drunk on a balcony ridiculously high up!
The main other thing I'd recommend is dinner in the Stratosphere as it rotates while you eat, very romantic if you're into that kind of thing!
I even smile while typing this, what a place! Also managed to spend £1k at the wheels during my time!!
Enjoy
