The Las Vegas Strip is amazing! I recommend walking the strip and exploring the hotels and all their different themes. My personal favorites are Caesars Palace, Wynn, Encore, Bellagio, Venetian, Cosmo, and Paris. Experiences within the strip: Thrill rides on top of the Strat/observatory deck, Las Vegas Observation wheel and zip line, Bellagio's Conservatory & Botanical Gardens, Bellagio Fountains (runs every 30 min during the day and every 15 min during the night), Famous Las Vegas sign located in the beginning of the strip by Mandalay bay, The Sphere, flower (Verbena) drink at the Chandelier bar at the Cosmo part of a secret menu, Shows, Las Vegas pool party, there are many speakeasies in the area, Clubbing, Bar hopping, and many many more!!!
Fremont is old school Las Vegas! located in downtown is full of hotels, bars, restaurants, street performers, zip line, and bright colorful lights! Best to explore at night.
Museum features signs from old casinos and other businesses. It tells the story of Vegas!
Grand Canyon West is about 3 hours from Las Vegas. There are great tours that pick you up straight from the hotel or you can rent a car.
This art installation is in the middle of the desert and only a 25 minute ride from Las Vegas Strip.
If you are interested in hiking or want a good photo op spot Red Rock Canyon is a great location and only about a 15 minute drive from Las Vegas Strip.
