Spontaneous travel sounds great until you're dragging a suitcase around at dusk with nowhere to sleep. Travel writer Rick Steves has spent decades perfecting the art of booking accommodation as you go, and his advice boils down to one rule: never accept a room sight unseen.

His core method is simple. Book the first night or two of a trip in advance, then secure each next hotel in the morning once you know where you'll end up that evening. That way you spend the day sightseeing relaxed rather than anxious, without losing the freedom to change plans on a whim. He flags one big condition: this works best in the off-season, when rooms are plentiful and cheaper anyway. In peak season, you'll be competing with everyone else for the same beds.

When you do find a room, Steves says inspect it before committing. Check the heating, listen for noise, and judge the general comfort. If it falls short, ask for a different room — or point out its flaws and the price may drop. If it's still no good, walk away. One caveat: in some hotels and some countries, policy won't let you view a room without booking it. It costs nothing to ask, though, and staff are usually accommodating. If you can't get inside, check guest-uploaded photos on Google Maps and Tripadvisor, which tend to be far more honest than official hotel imagery.

Stuck late in the day with options thinning out? Steves recommends same-day booking apps like HotelTonight, which covers many US cities and several other countries. He also suggests calling hotels between 9 and 10 a.m., when check-outs free up rooms — and, if one place is full, asking the manager where else to try. "Nobody knows the hotel scene better than hotel managers do," he says, and they'll often ring a nearby property on your behalf.

And if everything fails? Leave what Steves calls the "trouble zone" entirely. Roughly an hour away by car, train, or bus, there's usually a quieter, lesser-known town — the kind travel expert Samantha Brown calls a "B-side city" — where rooms are rarely full. You might pay a bit more or sacrifice some comfort, but you'll have a bed, and you might discover a place you'd never have found otherwise.

For travellers who hate rigid itineraries, this is a genuinely useful framework: anchor the start of your trip, book mornings, inspect rooms, lean on managers and review photos, and expand your radius when a city is full. Structure where it helps, freedom where it counts.
