Pregnant in Vegas

Just wondering if any of you ladies have gone to Vegas while pregnant. How was it? What did you do? What didn't you do? We are going in October. It's a bachelor/bachelorette/graduating nursing school/my 21st birthday/baby shower/wedding shower like all combined into one haha obviously I will not be drinking, and I will not be hanging around in the casinos more than needed (just walking through, maybe playing slots for a few minutes) because of the smoke. Obviously won't be going on rides or anything. Just curious what you ladies did and didn't do.
