Undoubtedly, the first night of a Vegas vacation is the best night. But it’s also the most dangerous night for your wallet. The excitement, the promise of an unforgettable experience, and the presence of friends, family and friendly strangers all might compel you to be a little more generous than normal. In those moments, it’s easy to blow most of your budget on a fancy dinner and several rounds of drinks for everyone and their mom. But don’t worry if you’re almost out of cash after day one, because you can easily budget an entire day in Vegas for under $100. (Taxes, fees and tip are not included. Prices subject to change.)

Throughout the day, you’re going to need some sustenance, so it’s important to plan out your meals ahead of time. You won’t be able to eat like a king under a $100 budget, but you can get by with some good eats. For breakfast, PBR Rock Bar & Grill (Planet Hollywood Resort, 702.750.1685) offers a classic breakfast with two eggs, bacon or sausage patties, mixed fruit and toast for only $6.

The next two are interchangeable depending on what you’re feeling at the time, but we suggest heading to Blue Ribbon Fried Chicken (Grand Bazaar Shops, 702.800.0404) for lunch and ordering the classic fried chicken sandwich for $10. Then, for dinner, stop by Shake Shack (New York-New York, 725.222.6730) for a ShackBurger and an order of fries for $10. Don’t forget a side of ShackSauce!

Checking out Las Vegas attractions is the best way to save some cash, because many of them are free. At the 4-acre Wildlife Habitat (Flamingo, 702.733.3349), you can see more than 300 birds, such as Chilean flamingos, swans, songbirds and more, hanging out in a lush, exotic environment. There’s even a tranquil koi pond. Then, down the street you’ll find the world-famous Fountains of Bellagio, an elegant water show that always impresses, no matter how many times you’ve seen it.

One attraction you can spend hours exploring is REAL BODIES at Bally’s (702.777.2782). For $30, this exhibit, which features delicately preserved human bodies, will not only inform you about the inner workings of your body, but it might also make you think more deeply about what it means to be human.

As the night begins, and the city comes alive, you’ll be tempted to splurge, so we’ve saved the greatest expense for last. You’ll probably want a fancy cocktail, and the average price range on the Strip these days is around $18-$22. So if you’re going to spend top dollar, it’s best to head to The Dorsey (The Venetian, 702.414.1945), a swanky lounge that blends modernity with timeless elegance. The Penicillin ($18) is a favorite cocktail, a mix of Scotch, lemon, ginger, honey and Islay float.

End the night with one of the most stunning views of the city at The STRAT Skypod. Admission ($25) gives you access to both indoor and outdoor observation decks atop the tallest tower in the city, capping off a day in Vegas for under $100, with a dollar to spare.
