My best hacks for a short getaway would be saving money on the small things so you can enjoy yourself more out there!
💦bring an empty water bottle to the airport (and fill it up after security)
💳use a travel credit/debit card
🏥a valid EHIC/GHIC card just in case something goes wrong, this can save time & money and help you get back on track with your spontaneous getaway
👕wear your layers so there's more space in your carry on (who knows how much shopping you can do in 24 hours)
🎙️talk to everyone, the flight, the bus, the hostel/hotel, the best recommendations come from others
