We like to come here from time to time whenever we are in Vegas. It provides a different experience from the strip. Everything is less expensive here. This is what old Vegas is about.
There are lots of things to do here from the casinos, restaurants, bars and shops. They also have a zipline overhead which zips through the length of the street. Of course, in Vegas they have street performers everywhere and here is no exception.
The best time to visit Fremont street is during the night when they have the light show overhead that plays every hour for a few minutes. It is very entertaining especially with the music.
Park at the Golden Nugget casino. You can get your parking ticket validated at the Starbucks (with purchase) or Claim Jumper inside the casino.
