How to use AI to plan a road trip

You have five days off, a car with decent tires, and a plan that reads “drive somewhere nice.” Your sister wants mountains. Your kids want a pool. You would like to not drive 9 hours in one day.

AI is good at turning a pile of wishes into a draft itinerary. In about 30 minutes you’ll have a day-by-day plan, stops worth checking out, and a budget built on your own numbers. Your maps app does the fact-checking.

What you’ll end up with

A day-by-day draft with driving times, overnight stops, and things to book, plus a simple budget.

Before you start

Where you’re starting and ending, your dates, and the most hours anyone wants to drive in a day
Who’s coming, and what each person cares about
A rough total budget
Your car’s miles per gallon (or range, if it’s electric) and the current gas price near you

Step 1: Describe the trip you want

Give the AI your limits first and your wishes second. Without limits, it will cheerfully suggest a 12-hour Tuesday.

Help me plan a road trip. Draft a day-by-day itinerary.

Starting point: [CITY, STATE]
Ending point: [CITY, STATE, OR "BACK HOME"]
Dates: [START DATE] to [END DATE]
Maximum driving per day: [HOURS]
Travelers: [WHO, WITH AGES IF KIDS]
What we want to see or do: [E.G. MOUNTAINS, A POOL AT THE HOTEL, GOOD BARBECUE, ONE MUSEUM]
What we want to avoid: [E.G. BIG-CITY TRAFFIC, CAMPING, LONG HIKES]
Total budget: [AMOUNT]

For each day, list: the route, approximate driving time, one or two suggested stops, and the town to stay overnight.
Never exceed the maximum driving time on any day. If that's impossible with my dates, say so and suggest what to change.
Double-check each day's drive time before answering.
Route around large cities where reasonable, and tell me when a route goes through one.
Mark driving times as approximate. If you're unsure whether a place is open in my travel dates, say so instead of guessing.
Don't propose a budget unless I ask.

The “maximum driving per day” line does the most work. Two people in the front seat may love a long haul. The two in the back seat have opinions about it after 4 hours.

Step 2: Check the route in a real maps app

This step isn’t optional. Plug each day’s route into Google Maps, Apple Maps, or Waze and compare drive times. If a day runs long, tell the AI the real number and ask it to rebalance.

In one of our tests, ChatGPT’s first itinerary said it kept every day under our 5-hour cap, then listed Day 1 at “4 hr 45 min–5 hr.” Further down the same reply, it admitted that day was “too close to, or beyond” the limit and offered a revised plan. It caught itself. Your maps app catches it sooner.

Step 3: Find stops along each leg

Ask for stops one day at a time, so the suggestions stay specific.

Try This Prompt

For Day [NUMBER] of the trip, driving from [TOWN] to [TOWN], suggest 5 places to stop along or near the route.

For each one, give:
- What it is and why it fits our group: [WHO'S COMING AND WHAT THEY LIKE]
- About how far off the main route it is
- How long a typical visit takes
- Whether it usually needs a reservation or ticket in advance

Only suggest places you are confident exist. If you're not sure a place is still open, say so.

What you might get back (illustrative example from ChatGPT for this step's prompt; results vary)

Trimmed from a real ChatGPT answer (logged out, October 15, 2026). The ”…” marks show where we cut.

Cadillac Ranch — Amarillo, Texas

…

Detour: Minimal; just off I-40 on Amarillo’s west side.
Visit time: 20–35 minutes.
Advance ticket: No; it’s a free, walk-up outdoor attraction.

The AI thinks every small town has “a charming historic downtown.” Some do. Look it up before you plan lunch around it.

Step 4: Build the budget from your numbers

The AI doesn’t know today’s gas prices or motel rates, so hand it your numbers.

Try This Prompt

Build a simple road trip budget as a table.

Total driving distance from my maps app: [MILES]
My car's fuel economy: [MILES PER GALLON]
Gas price I'm planning around: [PRICE PER GALLON]
Number of nights: [NUMBER]
Number of days to budget food for: [NUMBER]
Lodging cost per night I found: [AMOUNT]
Food budget per person per day: [AMOUNT]
Number of people: [NUMBER]
Tickets, parking, and admissions I know about: [LIST WITH PRICES]

Show the math for gas. Add a line for unexpected costs at 10% of the subtotal. Put the total at the bottom of the table and don't state a different total anywhere else. Then tell me whether it fits my total budget of [AMOUNT], and if it doesn't, suggest three specific ways to cut costs.

Then check the math on a calculator. In an early test, the table added up, but the opening sentence gave a different, higher total. One answer, two totals, total confidence in both.

When it goes sideways

The days are too packed? Say “Cut this to one main activity per day, plus meals.”
The suggestions are generic? Add detail. “A 10-year-old obsessed with dinosaurs and a grandmother with a bad knee” beats “family.”
A place doesn’t seem to exist? It may have made it up. Tell it, and ask for a replacement you can look up.
Rain on a big outdoor day? Ask for an indoor backup near that night’s town, and confirm it’s open. It beats a motel-room standoff.
