Travel is priced for two people. Accommodation is per room, tours charge a single supplement, and taxis do not halve. The gap is larger than most solo budgets account for.
Where the cost splits badly
| Cost | Solo penalty |
|---|---|
| Hotel room | Full price for one |
| Self-catering rental | Full price for one |
| Taxis and transfers | Full price |
| Private guide | Full price |
| Tour single supplement | +30% to +100% |
| Car hire | Full price |
Where it does not
Food, transport tickets, museum entry, group tours. All per person, and they are a large share of a trip.
Solo travel is also cheaper in one respect nobody counts: you eat what and when you want, which usually means less restaurant spending than a couple negotiating three meals a day.
The single supplement
An extra charge on tours and cruises for occupying a room designed for two, frequently adding 30 to 100%.
How to avoid it:
Operators who waive it on selected departures — several do, particularly outside peak season.
Roommate matching, where the operator pairs you with another solo traveller of the same sex. Free, and it works better than people expect.
Dedicated solo departures, which some small-group operators run.
Small-group operators accommodate this far more readily than large ones. Ask directly rather than assuming the listed price is fixed.
The destinations that price fairly
Japan — business hotels are built for the single traveller, with proper single rooms at genuine single prices. Capsule hotels go further. Japan is one of the few developed countries where solo accommodation costs what it should.
Southeast Asia — guesthouses with cheap private rooms everywhere, and eating alone at street stalls is completely normal.
Anywhere with a hostel private room — the social access of a hostel with a door that closes, at well below hotel prices.
Spain, Portugal and Italy's pensión, pensão and affittacamere — small guesthouses that frequently have genuine single rooms.
Where it is worst
Northern Europe and the Alps, where hotel rooms are priced for two and genuine singles are scarce.
Self-catering regions — the Dordogne, Tuscany, rural Ireland — where the accommodation model is a house.
Cruises and organised tours generally.
Safari and expedition travel, where supplements are steepest.
The practical adjustments
Hostels with private rooms rather than hotels, in cities.
Trains rather than car hire, since the car is the worst solo purchase in travel.
Join group tours rather than booking private guides.
Stay longer in fewer places, which cuts the transfers where solo pricing hurts most.
Eat lunch as the main meal, where fixed-price menus are per person and half the evening cost.
The realistic figure
Budget roughly 1.4 to 1.6 times what one person would spend on the same trip taken as a couple.
Not double, because so much is per-person, and not equal, because the bed is not.
