Every season there is a new display. The flowers are fresh and breath taking. Definitely a site to see if you have some free time.
High Roller allows a great observation view of Vegas. It also has Zip lining if you are interested. Groupon tends to have great deals for these two attractions.
Downtown Fremont is always a fun time. Late at night, it gets a bit wild. But visiting this area is a must to see old Las Vegas hotels like the Gold Nugget or 4 Queens Hotel. The newest hotel in Fremont is the Circa Hotel.
