Destinations that reward spontaneity

What makes a destination "last-minute friendly"

• Flight frequency: many daily connections mean competitive fares even inside a week, and easy recovery if something cancels.
• Hotel depth: tens of thousands of rooms means someone is always discounting. Small resort towns with 30 hotels are the opposite.
• Low booking bottlenecks: if the destination's headline experiences sell out weeks ahead (tiny museums, permit hikes, hot restaurants), spontaneity costs you the point of going.
• Cheap ground game: good transit from the airport and a walkable core keep the "hidden second budget" small.

Each city guide covers all four, plus when not to go and a realistic 48-hour plan. Use it with the core playbook and the weekend framework.
