Seaoned traveller or first timers will throughly enjoy the Fremont Street Experience! There is definitely something for everyone, from the gambler, to the thrill seeker (they have zip lining!!), to the shopper (bargain souviers compared to the strip) and artists alike!
The feel of downtown really reminds me of New Orleans...the street fair vibe. Tattoo shops sprinkled with bars...artists on the street trying to make a few bucks. You should definitely check out the guys spray painting the Las Vegas skyline on paper. It's as classic as getting your name written in Chinese in Times Square!
I've been to Vegas a half dozen times and this was my first time down on Fremont...my friends that are locals love to hang out here on a Saturday night. If you're in the area, be sure to stop by.
