Galloping Ghost outside Chicago and Pinball PA outside Pittsburgh are also great places to check out if you like pinball.
But yes, there’s plenty of stuff to do in Vegas beyond the obvious. My favorite: Red Rock Canyon just west of Vegas is beautiful for hiking!
I lived in Vegas from 2009-2012, and I used to always park at the Bellagio whenever I took tourist friends to the strip. My mom used to always tell me "Yeah, parking is free because the casinos pay for it!" Sad times now that that's no longer the case :(
At least the casinos' tax revenue still makes up for a lack of a state income tax...right?
Years ago, sadly. And it's not just that it's no longer free, it's actually creating more traffic. The whole Vegas experience is non-trivially worse for it.
The parking charges are a pain. Previously I would just pick up a car at the airport if I were using it to go somewhere like Death Valley after a four-day conference or so. Now it makes more sense to either rent a car at one of the hotels or just go back to the rental car center at the airport.
But yeah, the surroundings of Las Vegas are great for nature lovers: Red Rock, Valley of Fire, and Mount Charleston are all within an hour drive, and there are a good number of national parks within day tripping distance.
Thankfully we were there in march.
I'm not familiar, are the hotel pools free/public? Or are you just implying you walk in like you belong, and they don't check if you're a guest at the hotel?
Edit: A few of the pools allow swim-up gaming. I believe they are legally required to allow you into their pool if you say you want to play blackjack there, since they can't offer private gaming
Edit 2: Some of the casinos have "Pool Parties" or "Day Clubs" or whatever, usually loud, booze-soaked affairs with big-name DJ's, which you do not have to be a hotel guest for, but you do need to buy tickets.
