My mom, boyfriend, and I are leaving in about 3 weeks for our first trip to Vegas, celebrating my 21st birthday! By now, all the basics are set in stone. Airfare is booked, hotel is booked (MGM Grand). Now I'm compiling a list of must-do activities. Favorite casinos? Special drinks? Fabulous dining? I'm eagerly anticipating whatever suggestions you have to offer! I've included the basics thus far - Bellagio fountains, Mirage volcano, etc. Now I'm looking for some first-hand unique experiences. Thanks in advance!
