My little sister is taking her first trip to Vegas next spring and naturally asked me for suggestions on what to do. After rattling of several must see things,(Bellagio water fountains,TI pirate show,Hoover Damn, Fremont Experience,etc.), I started mentioning what I consider to be fun but often overlooked stuff by most people who visit Vegas. That led me to wonder what others thoughts were. Maybe I'll learn something and on my next trip see or do something that I otherwise would have overlooked. So my question to everyone is: What do you think are fun things to do or see but often overlooked by most people who visit Vegas?
