Travelling alone and travelling together are different jobs

Every group decision has an overhead

Two people travelling together face a decision roughly every hour: when to leave, where to eat, whether to stop, how long to stay in a room, whether to walk or take the bus. Each of those has to be converted from two preferences into one action, and that conversion takes time and a small amount of goodwill.

With four or five people the overhead grows faster than the number of people, because the range of preferences widens and the chance that everyone wants the same thing falls. This is why large groups move slowly and why departures take so long, and it is arithmetic rather than anybody being difficult.

Travelling alone removes the overhead entirely. You change your mind at no cost, follow something because it looked interesting, eat at an odd hour and leave when you have had enough, and none of it requires negotiation. That freedom is the single most cited reason people give for travelling alone.

What a group provides that solitude cannot

The compensations are substantial and mostly unglamorous. Someone watches the bags while you buy tickets. Somebody else reads the map. Costs that are charged per room or per vehicle are split. There is a second opinion on whether an area feels wrong, and a second person to deal with it if something goes actually wrong.

The shared memory is the part that is hardest to replicate. Experiences you had with someone remain available to be talked about years later, whereas solo experiences exist only in one head and are unexpectedly difficult to convey afterwards.

There is also a practical point about depth of engagement with a place. Solo travellers generally speak to more strangers, partly because they have to and partly because they are more approachable, so a group often has a better trip together and a thinner encounter with where they are.

The costs of travelling alone are real and specific

Money is the first. Single occupancy is frequently charged at close to the price of a double room, taxis and vehicles do not divide, and package products are commonly priced with a supplement for one person, so the same trip simply costs more per head.

Logistics are the second. Nobody can watch your bag, hold a place, collect a ticket while you queue elsewhere, or wait with the luggage while you look at a room. These are small frictions individually and they accumulate over a long journey.

And there is the plain fact that some places and some hours feel different alone, in ways that vary a great deal depending on who you are and where you are. That is not a reason not to travel alone, but pretending it is identical for everybody is not honest.

Arrangements that get some of both

Most experienced travellers end up mixing. Travelling alone but staying in places with common space produces plenty of company without any obligation. Meeting friends for part of a trip and continuing alone gives you the shared portion and the free portion.

Within a group, the most reliable improvement is to split up during the day and reconvene in the evening. It removes the hourly negotiation entirely, lets people follow their own interests, and turns dinner into an exchange of two different days rather than a summary of the same one.

Agreeing in advance how decisions get made is less romantic and more effective than it sounds. Who books, who decides when opinion is split, and whether people are free to opt out of any given plan are worth establishing before the trip rather than discovering on day three in a station.

Choosing on the basis of what the trip is for

Some trips genuinely favour company. Anything with a fixed shared cost, anything remote where a second person is a margin of safety, anything involving driving long distances, and anything whose point is being together rather than being somewhere.

Others favour solitude. Long slow journeys where the pace should be free to change, trips built around a specific personal interest that nobody else shares, and anything where the goal is to pay close attention to a place rather than to a conversation.

The honest conclusion is that this is a preference rather than a hierarchy, despite the way solo travel is sometimes written about as a superior state. The two produce different trips, and someone who only ever does one of them is missing what the other is good at.
