The fully booked restaurant at 8pm on Saturday. The museum entry that sold out three weeks ago. The hotel that looked fine on paper but put you forty minutes from everything. These are not bad luck. They are the cost of under-planning, and they're avoidable.

The Myth That Spontaneous Is Better

Spontaneity is appealing in theory because it sounds like freedom. In practice, the freedom to turn up at a good restaurant on a Saturday evening without a reservation is largely theoretical. The freedom to walk up to a popular museum and buy a ticket on the day exists only outside peak season at mid-tier attractions. The freedom to find a great centrally located hotel the week before you travel will cost you more than booking three months ahead.

The spontaneous trip often ends up being a collection of second choices. The restaurant you ended up at because the one you wanted was full. The museum you visited because the one you planned wasn't accessible. The neighbourhood you stayed in because the good hotels were gone.

What to Pre-Book

Flights, obviously. Accommodation, with cancellation flexibility where possible. Timed entry to any attraction that regularly sells out: this list includes the Anne Frank House, the Sagrada Familia, the Colosseum, the Uffizi, the Vatican, Versailles. One restaurant per trip minimum, the one you'd be genuinely disappointed to miss.

Transfers from the airport if you're arriving late or have a long journey with luggage. Any experience that has limited capacity: a cooking class, a wine tasting, a specific guided tour.

What Not to Pre-Book

Every meal. Every afternoon activity. Every hour of every day. These are the things that benefit from flexibility, because your energy and preferences on the day are impossible to predict accurately before you leave. Over-booking these removes the ability to respond to what the city is actually offering.

The 80/20 Structure

Book the anchors. Leave the rest. Anchors are the things with limited availability and high consequences if you miss them. The rest is everything that will resolve itself when you're there. A trip with well-booked anchors and open space between them is more enjoyable than either extreme: fully scripted or entirely unplanned. The anchors give you things to look forward to. The open space gives you permission to be surprised.
