FYI, Circus Circus to the nearest Walmart (Charleston) is a 4.1 mile drive, or about 10 minutes. Those of you staying at the Westgate can expect a drive just slightly longer, at 4.2 miles.
The nearest one to you will depend on which part of the strip your hotel is situated. In general however, when staying on the south end of the strip (by the airport), the store at 3075 E. Tropicana Boulevard, is the nearest Walmart to the Strip, at 3.5 miles away (or 5.6 kilometers). This is figured when starting from the intersection of Las Vegas Boulevard and Tropicana Avenue.
Road trip!!! Don’t forget to blast the as you escape the city and make your way to the nearest Walmart Supercenter. Try to do some research first and find one that has a firearms/ammunition department. You don’t want to have to stab a zombie and get weird zombie guts all over your brand new zebra print Snuggie that you just picked up in aisle 7.
