You're finally here! After landing and dropping your bags, you'll dive straight into Barcelona with a walk down Las Ramblas and through the Gothic Quarter. Take a power nap because tonight you're hitting the pub crawl that comes free with your hostel stay – it ends at a club, so pace yourself but don't hold back.

Today's all about Gaudí – you'll see the Sagrada Família (book ahead, it's worth every euro) and Park Güell, two places that'll make you question how one person could be so creative. After soaking in the architecture, wander through Gràcia for dinner and drinks, then hit El Born for a chill bar hop. Keep it mellow tonight because tomorrow's your big night out.

Start with Picasso in the morning, then hit the beach for lunch at a chiringuito – this is the Barcelona vibe. Casa Batlló's rooftop is absolutely worth the splurge, and sunset drinks at the W Hotel will set the mood. But the real star tonight? This is your BIG NIGHT. Razzmatazz or Opium – both are legendary. Full send, no regrets.

Sleep in, you've earned it. Take the cable car up to Montjuïc for the best city views, then hit the Christmas market for some festive vibes. Your farewell dinner at Cervecería Catalana is the best tapas spot in the city – go hungry. One last Barcelona night, but keep it reasonable since you're flying to Lisbon tomorrow.

Quick flight to Lisbon and you're in a whole new world. Your loft in Príncipe Real is going to be amazing – way nicer than the hostel. After settling in, you'll explore the neighborhood and Bairro Alto, then cap off the night with an authentic Fado dinner. The music will give you chills, and then the bars spill onto the streets. Welcome to Lisbon.

Head to Belém for the UNESCO monastery and the original pastéis de nata – get them warm, they're life-changing. The Belém Tower and Monument to the Discoveries tell the story of Portugal's golden age. Back in the city, grab wine from a shop and watch sunset from a miradouro, then hit Pink Street. Thursday nights here are wild.

São Jorge Castle has the best views in the city – you'll see all of Lisbon from up there. Ride the iconic Tram 28 through the narrow streets, then get lost in Alfama's maze of alleys. Time Out Market for dinner is a food hall with the best chefs in the city, and then Pensão Amor (yes, it was a brothel) is one of the coolest bars you'll ever see. Friday night in Cais do Sodré is electric.

Sintra is like stepping into a fairytale – colorful Pena Palace perched on a hill, mystical Quinta da Regaleira with underground tunnels you can explore. It's only 40 minutes from Lisbon but feels like another world. Book your tickets ahead, especially for Pena Palace. Back in the city, keep it chill at dinner because tonight you're hitting Lux Frágil – Lisbon's best club, right on the river. Saturday night here is legendary.

Sleep in, you need it after Lux. LX Factory is a converted industrial complex with the best brunch spot (get the chocolate cake at Landeau, it's famous for a reason), vintage shops, and street art everywhere. The MAAT Museum has wild architecture, and then a sunset walk along the river. Keep it chill tonight – you've got one more big night tomorrow.

Cervejaria Ramiro is legendary – go early because the lines get insane, but the seafood is worth every minute. Then take the train to Cascais, a beautiful coastal town just 30 minutes away. Walk the promenade, breathe in the ocean air. Back in Lisbon, pack your bags, have one last dinner in Bairro Alto, and then go all out. Your flight isn't until 11:55 AM tomorrow – you can actually sleep in, so make this last night count.

One last morning in Lisbon. Your flight leaves at 11:55 AM – no crazy early wake up call, which is perfect after last night. Leave the loft by 9 AM, get to the airport, and you're on your way home. What a trip.
