I did both The Strip and Fremont Street during my stay.
Fremont Street reminded me of AC-the type of place to people watch with a degree of unseemliness. Actors walk around in costumes ala LA posing for photos. There's dancers dancing provocatively on a stage.
Theres a show every hour at night. I always thought the show was a light show, visual show spectacular. Turns out the nightly show is a music video being shown on the canopy. Sorta blah to me.
It was worth a visit at least once.
