The all you can eat buffet experience we sampled was at THE WYNN ... can totally recommend this, it was spectacular !!
Other things to do as some of the Guys have already noted ....
Gun Store
if you do a helicopter ride - make sure its Maverick, not Heli USA !
See who's on at Ceasars Palace - we saw Elton John and that was amazing.
Cirque - we saw the Beatles one and yeah it was good.
There is just soooooooo much in Vegas - love the place data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7
Another recommendation here for a helicopter ride, we used Papillion and they were superb
We used Maverick too.
Saw Jersey boys last year at the Paris Hotel - excellent show - still on.
Used Maverick and Papillon - Maverick was my favourite.

Rehab, get a Cabana and party like a rock star.
Please note the copter trips do not go to GC south rim. No commercial aircraft are allowed here.
I drove from Vegas to the south rim and stayed overnight at the south rim in one of the lodges there.
Was fantastic seeing the real canyon instead of the Indian reservation area which the helicopters take you to.
Just about to land in Vegas, got to love airplane wifi.
Keep us posted!!!
