Ask anyone who has travelled for a long time what they would tell their earlier self and the answer is almost always the same sentence. Ask anyone planning their first long trip whether their itinerary has too many stops and the answer is always no.

This piece is an attempt to make the argument in numbers rather than as a sentiment, because the sentiment does not seem to work.

The arithmetic of a travel day

A journey between two places costs more than its duration.

A four-hour bus is: check out by ten, an hour to the station, four hours travelling, an hour finding the new place, and check-in at three. That is most of a day, and the evening is spent working out where anything is.

Then the next morning is spent orienting — which street has the market, where the bus station is, what things should cost. You do not start getting anything out of a place until roughly the second morning.

So a two-night stop is: one travel day, one orientation day, and you leave. You have paid a day of your trip for a day of confusion.

A four-night stop in the same place costs the same one travel day and gives you three usable ones.

What actually changes when you stay

The first day you are a tourist. Everything is being seen for the first time and evaluated.

By the third day you have a routine — a café, a route to the centre, a shop where they recognise you. Prices stop being negotiated because you know what things cost.

By the fifth day people talk to you differently. You are no longer someone who is passing through, and the conversations change accordingly.

By the second week you are bored, and boredom is where a place stops being a sequence of sights and becomes somewhere with ordinary life in it. Almost every good story from a long trip happens after the boredom, not before.

You cannot buy any of that with more destinations.

The costs go down too

Weekly and monthly accommodation rates are routinely 30 to 50 per cent below the nightly rate, and they are almost never advertised. Ask.

Transport is the largest variable cost on most trips, and it scales directly with how many places you go.

You stop paying tourist prices once you know what things cost and where the market is.

You cook sometimes, which is impossible when you change city every second day.

A month in one place is frequently cheaper than two weeks moving.

The counter-argument, taken seriously

There is a real case for moving fast: if you have ten days and will not return, seeing five things beats seeing one thing thoroughly. Some places genuinely are worth a day — a single site, a single view — and building a week around them is padding.

The honest version of the advice is not “always go slowly”. It is: decide which places you are passing through and which you are staying in, and stop pretending the passing-through ones are anything else. A one-night stop for one specific thing is fine. A trip made entirely of one-night stops is a logistics exercise.

How to actually build a slower trip

Halve the list. Take your itinerary, remove every second stop, and give the time to what is left. This is uncomfortable and it is right almost every time.

Set a minimum. Three nights anywhere, four in a city. Anything that cannot justify three nights probably does not need a night at all.

Use one base for a region. Day trips from a single town beat moving hotels every second day, and you unpack once.

Leave a fifth of the trip unallocated. The best part of most trips is the thing that was not planned, and it needs a gap to happen in.

Book two nights, not the whole route. Committing to a chain of reservations is what makes people leave places they are enjoying.

The version of this that matters most

On a trip of two weeks, going slowly means seeing four places instead of seven.

On a trip of six months, it means the difference between a trip you remember as a sequence of bus stations and one you remember as a set of places where you knew somebody’s name.

Nobody comes back from a long trip wishing they had seen more countries. A significant number come back wishing they had stayed longer in three or four of them.

What it looks like in practice

A fortnight in Vietnam done fast is Hanoi, Ha Long, Hue, Hoi An, Nha Trang, Ho Chi Minh City and the Mekong — seven stops, six travel days, and about five usable ones.

The same fortnight done slowly is Hanoi and Ninh Binh, then Hoi An, then Ho Chi Minh City — three stops, two travel days, and eleven usable ones. You see fewer places and considerably more of Vietnam.

The version people regret is almost never the second one.

The one exception worth naming

Somewhere you are certain you will return to can be sampled. If you live two hours’ flight from a city and will be back, a weekend that skims it is a reasonable use of a weekend.

The trip that should not be rushed is the one you are unlikely to repeat: the long-haul, the once-in-a-decade, the sabbatical. Those are exactly the trips people cram hardest, on the reasoning that they will not be back — which is precisely the reasoning that guarantees they will remember very little of it.
