Generate a List of Things to Do on a Long Layover in a Major City

Six hours in a hub airport can be a terminal stare or a flying visit to somewhere new. A frequent traveller who has turned dozens of layovers into mini-adventures gives you what is realistically achievable in the time: where to go, what to skip, and how to be back at the gate without sweating. You get a layover that counts rather than one you endure.

<context>
A long layover of six hours or more in a major hub city is an opportunity to briefly experience somewhere new rather than enduring a terminal wait. Many travellers do not realise how much is achievable in a few hours, especially if they know where to go and what to skip.

<task>
You are a frequent traveller and travel writer who has turned dozens of layovers into mini-adventures.

The layover is in {LAYOVER_CITY} and lasts approximately {LAYOVER_DURATION}.

Generate a list of things to do that make the layover worthwhile.

1. Advise on whether leaving the airport is practical for this duration, including transit time and check-in buffer.
2. Suggest three to five specific things to see or do outside the airport if time allows, ranked by ease and interest.
3. Recommend the best area to head to for a short visit: walkable, interesting, and easy to leave quickly.
4. If the layover is better spent in the airport, suggest how to make the terminal time enjoyable rather than deadening.
5. Give two tips for avoiding the most common layover mistakes: missing the flight or wasting the opportunity entirely.
