Now that you know how old you have to be to gamble in Vegas, you might want to look elsewhere. Like gambling, the legal drinking age in Nevada is also 21. As such, you should check before booking any accommodation that an age restriction doesn’t apply. It’s also worth noting that many hotels in Vegas do not allow guests under the age of 21 to stay at their venues. The legal gambling age of 21 also applies to the rest of Nevada, so you won’t be able to try your luck elsewhere in the state.
