Why it matters

Every other decision hangs off this one. Dates, flights, how we get between cities, and which city pages are even relevant all follow from it.

The original idea was Greece, Italy, and Spain. Adding Paris, London, and Amsterdam to the candidate list surfaced a real problem: those are two different trips. The southern countries are a wide arc connected mostly by flights. The northern cities are a tight cluster connected by fast trains. Merging all six countries into two weeks means roughly five intercity legs and about a third of the trip in transit.

Two weeks realistically supports three or four bases. So we pick a lane.

The options

1. Mediterranean — Athens · Rome · Barcelona or Madrid

The original plan. Mild and bright: January highs of 11–15 °C (52–59 °F) across these four cities, and in Madrid the sun is up until nearly 6:00 PM. Ancient sites and museums are at their least crowded all year.

The cost is transit. There is no useful rail between Greece, Italy, and Spain, so each move is a flight with airport time on both ends. Athens is the outlier — two hours from Rome, further from everything else.

Also worth saying plainly: the Greek islands are out either way. Santorini and the Cyclades largely shut down in winter. Greece here means Athens, a city trip.

2. Northern classics — London · Paris · Amsterdam

By far the tightest logistics on offer. London to Paris is 2h20 by Eurostar and Paris to Amsterdam about 3h20, both city center to city center with no airports involved. Three countries, two train rides, zero transfer stress.

It is also the strongest option for Bubu and Gaby. West End theatre, Camden, the Louvre, the Amsterdam Light Festival, no language barrier in London — these land better at 17 and 18 than a fourth archaeological site.

The catch is darkness and weather. Late-December sunsets: London 3:53 PM, Amsterdam 4:29 PM, Paris 4:55 PM. Highs of 6–8 °C (43–47 °F), frequent rain. You are touring in the dark and the wet for a meaningful part of each day. Christmas markets and the Light Festival partly turn that into a feature, but only partly.

3. Split arc — e.g. Rome · Barcelona · Paris · London

Covers both moods: Mediterranean light at the start, northern cities at the end, finishing with an easy English-speaking base and a straightforward flight home. Rome to Barcelona is a 2-hour flight, Barcelona to Paris a 2-hour flight or 6.5-hour train, Paris to London 2h20 by train.

It drops Greece — the geographic outlier — and spends the most days moving. Four bases in fourteen days is a brisk pace with a lot of packing.

My recommendation

Option 3, the split arc, if the group can tolerate the pace. It gets the Mediterranean daylight that makes the first week pleasant and the northern cities that the kids will actually remember, and it ends somewhere with a lot of direct flights home.

If the group would rather move less, option 1 without Athens — Rome, Barcelona, Seville — is the most relaxed and the sunniest version of this trip.

I would not choose option 2 as a first Europe trip for this family. London and Paris are wonderful and you should absolutely go, but a fourteen-day trip where it is dark by 4 PM every day is a hard sell against the alternative.

What would change my mind

• If we go over Christmas and New Year’s specifically — the northern arc gets stronger. Christmas markets and the Light Festival are genuinely better than anything the south offers in that window.
• If Bubu and Gaby say the northern cities are the whole point — that settles it. See What do the kids want?.
• If we would rather do three nights in four places than five nights in three — pace tolerance is the real constraint here, and I am guessing at it. See Pace.
