The downtown area is somewhat seedy that is highlighted by this Fremont Street Experience. This vaulted dome that flanks the promenade has light shows and also zip lining! I think that the zip lining would be a very good experience. However, don't park in the Fremont Street Experience parking lot because you can just park in one of the casino's parking lot and not have to pay a fee to park. 4 Queens, Binions, Fremont Casino, etc all are adjacent to the Fremont Street Promenade. There appears to be inexpensive souvenirs all around this area.
