Best known as the capital of Charlemagne's Frankish empire, today's Aachen sits at the juncture where Germany meets the Netherlands (the Dutch know it as Aken) and Belgium (where "Walloons" call it Aix-la-Chapelle). But Aachen's history goes back even further than 8th-century Charlemagne. Roman soldiers dating back to the 1st century AD cherished its hot springs (as did Charlemagne, who loved a good spa day just as much as the next guy). Aachen Cathedral, northern Europe's oldest and a UNESCO World Heritage Site, is the city's main attraction.

With its calm waters, sandy bays, and family-friendly vibe, Cala d'Or is an easy-going alternative to Majorca's more popular resort destinations. Charming cobbled streets wind past whitewashed buildings, and lengthy sunlight hours allow plenty of time for exploring the town's woodland surrounds.

Stroll Las Ramblas and enjoy Barcelona's unique blend of Catalan culture, distinctive architecture, lively nightlife and trendy, stylish hotels. You'll find Europe's best-preserved Gothic Quarter here, as well as amazing architectural works by Gaudi. La Sagrada Familia, considered Gaudi's masterpiece, is still under construction (your entrance fee helps to fund the project). Feel like a picnic? Look no further than the rambunctious La Boqueria market, where you can stock up on local delicacies.

From Shoreditch’s swaggering style to Camden’s punky vibe and chic Portobello Road, London is many worlds in one. The city’s energy means that no two days are the same. Explore royal or historic sites, tick off landmarks from your bucket list, eat and drink in exclusive Michelin-starred restaurants, enjoy a pint in a traditional pub, or get lost down winding cobbled streets and see what you stumble across – when it comes to London, the possibilities are endless.
