London + something is a common 2-week itinerary. Here's the honest sort.
Best London combinations
- London + Paris: Eurostar 2h 30min. The classic. 5+ nights each.
- London + Edinburgh: 4h 20min train. 5 + 4 nights with Highland day-trips.
- London + Dublin: 1h 15min flight. 5 + 4 nights.
- London + Amsterdam: 4h Eurostar to Amsterdam direct (recent). 5 + 4 nights.
- London + Berlin: 1h 50min flight. Both major capitals.
Trickier London combinations
- London + Rome: Fly 2h 35min. Both deep cities; need 6-7 nights each.
- London + Barcelona: Fly 2h 15min. Different vibes.
- London + Brussels + Bruges: Train via Eurostar; logistical small-trip.
- London + Iceland: 3h flight. Different climate but works for Northern Lights season.
What doesn't work in 10-14 days
- London + 4 other cities: Half is travel.
- London + Greek islands: Logistics eat time.
- London + Russian capitals: Politics aside, distance.
Strategy
For 10-day London-anchored trips, pick 1 partner city. For 14 days, 2 partner cities maximum. Eurostar makes Western European combinations easy; Northern Europe needs flights.
