Nothing to worry about. Vegas is as normal (or as crazy) as you make it. If you need any pointers while you are here, don't hesitate to contact me! I can gurantee you that I've been to places a lot more chaotic than Vegas. :P
P.S. There is no smoking in MOST public places here now...aside from inside the casinos. If you want to gamble and stay out of smoke, the poker rooms are always smoke free
