If you stay at Main Street Station you'll enjoy the old neon signage as you drive Las Vegas Blvd. Good and reasonable buffet at MSS, best not to wander the streets at night. A couple blocks away is Fremont Street Experience which should be just fine at night. I just buzz over to the Plaza and park in their parking structure. You can get your ticket validated inside the casino. If you want to see comments on it follow the link below.
