In seven days, you’ll sample two worlds that couldn’t be more different: Las Vegas, all neon theatre and desert horizons, and Dublin, a city of storytellers where Georgian squares meet the River Liffey. This itinerary balances headline sights with genuine local flavor, from tacos on the Strip to trad sessions in hidden pubs.

Las Vegas grew from a railroad stop to the entertainment capital of the world, equal parts spectacle and gateway to the American Southwest. Dublin, founded by Vikings and shaped by poets, pairs history with a first-rate culinary and coffee scene. Both cities reward curiosity—wander a block or two off the main path and they open up.

Note on your original list: Antarctica and Fiji shine best on dedicated trips—Antarctica typically requires a 10–12 day expedition cruise (Nov–Mar from Ushuaia), while Fiji deserves at least a week to enjoy its islands. For this 7-day itinerary, we’ve focused on two destinations that fit the timeline and keep travel realistic: Las Vegas and Dublin.

Las Vegas

Vegas is a mirage of light in the Mojave: grand hotels themed like cities, world-class dining, and shows that flirt with the impossible. Beyond the Strip, the Arts District hums with indie galleries, craft coffee, and some of the city’s most exciting kitchens.

• Icons: Bellagio Fountains, Fremont Street, the “Welcome to Fabulous Las Vegas” sign.
• Nearby nature: Red Rock Canyon’s rust-red cliffs, Valley of Fire’s alien arches, day trips to the Grand Canyon and Hoover Dam.
• Where to eat (highly current): Lotus of Siam (Northern Thai classics), Best Friend by Roy Choi (Korean-Mex vibes), Esther’s Kitchen (house-made pastas in the Arts District), Tacos El Gordo (Tijuana-style adobada), Peppermill (retro diner/lounge), PublicUs and Vesta (top specialty coffee).

Day 1: Arrive Las Vegas

Afternoon: Land in Vegas and check in. Stretch your legs with a loop through the Bellagio Conservatory (floral art that changes seasonally), then catch the Bellagio Fountains—music-synced water ballet every 15–30 minutes.

Evening: Dinner on the Strip: try Best Friend by Roy Choi (Korean BBQ tacos, short rib, playful hip-hop vibe) or Lotus of Siam (northern Thai khao soi, crispy garlic prawns). Cap the night with a jaw-dropping city view on the Las Vegas Helicopter Night Strip Flight.

Day 2: Art, Coffee, and a Show

Morning: Coffee at PublicUs (DTLV) for impeccable espresso and breakfast sandwiches, or Vesta Coffee Roasters (Arts District) for single-origin pours and cardamom buns. Walk the 18b Arts District murals and vintage shops.

Afternoon: Dive into an alternate reality at Meow Wolf’s Omega Mart, a surreal supermarket that opens into secret portals and glowing “back rooms.” Pre-dinner aperitivi at The Venetian’s bar scene, or classic cocktails at the Peppermill’s Fireside Lounge.

Evening: See “O” by Cirque du Soleil, a waterborne fever dream with high divers, contortionists, and stagecraft that still astonishes. Late dinner at Esther’s Kitchen (house-milled flour pastas, blistered bread with ricotta), or tacos al pastor at Tacos El Gordo.

Day 3: Grand Canyon West + Hoover Dam (Day Tour)

Full-day excursion to Arizona’s sky-scraping geology with the Grand Canyon West with Hoover Dam Stop, Meals & Optional Skywalk. Expect scenic viewpoints like Eagle Point and Guano Point, optional Skywalk glass bridge, and a photogenic Hoover Dam stop. It’s a big day, but seeing the canyon’s vastness is worth every mile.

Day 4: Fly Las Vegas → Dublin

Morning: Breakfast at Sadelle’s (Bellagio) for smoked salmon towers or at Eggslut (The Cosmopolitan) for crowd-pleasing egg sandwiches. Head to the airport.

Afternoon: Fly to Dublin (typically 1 stop; ~12–15 hours total). Compare options on Omio (Flights). Typical one-way economy fares range widely by season (~$550–$1,100).

Evening: Overnight in the air. Adjust your watch for the 8-hour jump forward; hydration and a short walk every hour help with jet lag.

Day 5: Dublin’s Heart—Books, Bricks, and Breweries

Morning: Arrive Dublin and check in (or drop bags). Coffee at 3FE on Grand Canal Street—benchmark flat white—and a pastry. Then take priority access with the Book of Kells + St. Patrick’s + Dublin Castle tour for context, the Long Room’s oak-scented hush, and a gentle walk through the castle gardens.

Afternoon: Lunch at The Winding Stair (Irish brown bread, local cheese, seafood chowder) overlooking the Ha’penny Bridge. Stroll Grafton Street buskers, Stephen’s Green, and the Georgian doors of Merrion Square.

Evening: Pre-book the Guinness Storehouse; time your visit for sunset at the Gravity Bar for 360° city views with your pint. Dinner at Etto (book ahead; small plates like beef tartare, gnudi) and a nightcap at The Long Hall, one of Dublin’s most beautiful Victorian pubs.

Day 6: Cliffs of Moher & Galway (Day Tour)

See Ireland’s west in a day on the Cliffs of Moher, Burren & Galway tour. The coach traces the Wild Atlantic Way; on clear days you’ll watch seabirds wheel over 700-foot cliffs and wander Galway’s Latin Quarter. Expect an early start and late return; pack layers, as Atlantic weather changes swiftly.

Day 7: Dublin Easy Morning & Departure

Morning: Brunch at Brother Hubbard (shakshuka, mezze) or Queen of Tarts (buttermilk scones). Browse Irish design at Kilkenny on Nassau Street or peruse books at Hodges Figgis—then a final wander along the Liffey quays.

Afternoon: Head to Dublin Airport. Check flights on Omio (Flights). If your next leg heads beyond Europe, you can also compare options on Trip.com. Slán—until next time!
