Day 1 morning: settle on the Strip
Check in early on Las Vegas Boulevard. The Cosmopolitan and Aria on the central Strip put you within walking distance of Bellagio's fountains, which run every 30 minutes from 3pm and every 15 minutes after 8pm. Grab coffee at Sambalatte inside the Monte Carlo tower for around $6, then walk the pedestrian bridges between Planet Hollywood and Paris to get your bearings without dodging traffic.
For lunch, skip the buffets and head to Secret Pizza on the 3rd floor of the Cosmo. A cheese slice runs about $6 and the line moves fast even at 1pm. Back your room by 4pm to reset before the night shift.
Day 1 night: casinos and cocktails
Start with a $17 martini at the Chandelier Bar inside the Cosmopolitan, three floors of crystal-draped drinking that is the best introduction to Vegas nightlife you can buy. From there, walk south to the Aria poker room for lower-limit tables, or push straight to the Fontainebleau's LIV club if you want a proper 2am night. Cover charges run $30 to $75 depending on the DJ.
Late eats: In-N-Out on Linq Lane serves burgers until 1:30am for under $6. Cab back to your hotel, do not walk south of Tropicana after midnight.
Day 2: Red Rock and Valley of Fire
Pick up a rental car by 8am and drive 30 minutes west to Red Rock Canyon. The 13-mile scenic loop costs $20 per vehicle and takes about 90 minutes with photo stops at Calico Hills and High Point Overlook. Bring 2 liters of water per person; there is no shade.
If you have energy, push another 60 minutes northeast on I-15 to Valley of Fire State Park ($15 entry). The Fire Wave trail is a 1.5-mile round trip through striped sandstone and photographs best in late afternoon. Back on the Strip by 8pm for dinner.
Day 2 night: one big dinner
Book Bazaar Meat by Jose Andres at Sahara for 9pm. Expect $150 to $200 a head with a cocktail and a shared cote de boeuf. If that is over budget, Yardbird at the Venetian does a fried chicken and watermelon plate for $38 that is worth the flight alone. Cap the trip at the NoMad Library bar or, if you are still moving, the High Roller observation wheel, which runs until midnight at $25 a ticket.
Good to know
Do I need a car for 48 hours in Las Vegas?+
Only for day two. The Strip itself is walkable and the Deuce bus runs 24 hours for $6 a ride, but Red Rock and Valley of Fire need a rental. Turo or Enterprise near Harry Reid Airport starts around $55 a day.
Is 48 hours enough to see the Grand Canyon from Vegas?+
Not comfortably. The West Rim is 2.5 hours each way and the South Rim is 4.5 hours. If you only have 48 hours, stay in Nevada and save the Canyon for a longer trip.
What is the cheapest Strip hotel that is not a dump?+
The Linq and Excalibur run $45 to $90 a night midweek including resort fee negotiation. Both are central, safe, and clean enough for a two-night stay.
Can I gamble at 18 in Nevada?+
No. The legal gambling and drinking age is 21 statewide, and Strip casinos card aggressively at the tables and club doors.
