Either way, there is likely a sportsbook within walking distance of where you're staying. If there isn't one, there are a wide range of options in downtown Las Vegas and on the strip. If you're looking to bet right away, it makes sense to venture to the sportsbook where you're staying. That said, Vegas (and Nevada) is a little different than what most other states provide because they've been offering sports betting for decades.
Vegas remains the go-to place for sports betting even as states continue to legalize wagering throughout the country.
