yeh been there this summer - it's a crazy place & I wouldn't want to be there for too long (mainly because of the weather in summer - 45deg no exeption), but it's fun. It's one of those places you just have to see for yourself once in your life .

To do's in Vegas? Just check out all the casino's / hotels; walk around... It's one big theme park really and there's lots to see.. The New York, New York rollercoaster is fun (expensive though), Bellagio's fountain show, The Venetian,... Maybe go to one of the musicals / shows (prices are a bit steep, but it's worth it); I went to We Will Rock You (the Queen musical) in Paris Hotel / Casino - if it's still showing while you're there... check it out!

I'd recommend going out of Vegas for a bit too - the area has a lot to off as well; Hoover Dam, maybe Grand Canyon (which is quite a long way still), Colorado River,... Should be nice in winter too btw at least the temps won't be that bad as when I was there .
