How I Plan an Entire Trip With Claude, From Itinerary to Packing List to Budget

Planning a trip used to mean a dozen browser tabs, a messy notes app, and a packing list I'd forget to check. For my recent trip to Puerto Rico, I tried something different. I planned the whole thing with Claude, from the day-by-day itinerary to the packing list to keeping it on budget.

As a project manager, I treat trips like mini projects anyway. Claude just made the project a lot easier to run. Here's exactly how I did it, step by step.

Step 1: Decide where to plan it

Before I started, I asked Claude a simple question: should I make a Project for planning trips?

The answer depends on the trip. A Claude Project is great when you travel often or have one big trip with lots of moving parts. It keeps everything in one place, like your bookings, confirmations, and standing preferences ("I like walkable areas and mid-range hotels"), so you don't have to repeat yourself in every chat.

For a quick weekend getaway, a regular chat is totally fine. Pick whichever fits the size of your trip.

Step 2: Build the itinerary, then make it yours

I gave Claude the basics: where we were staying, how many days we had, and what we wanted to do. For us, that meant exploring Old San Juan, a rainforest hike, a day trip to one of the smaller islands, a bioluminescent bay tour, and plenty of time for photography.

Claude turned that into a full day-by-day plan with times, meal stops, backup options, and a few "good to know" tips for each day. It even planned around sunset so I'd catch golden hour for photos.

The best part is that it's not a one-shot deal. When I looked at the plan and thought, "This Sunday starts way too early," I just said so. Claude pushed the whole day later and was honest about the trade-off: the streets would be a little busier, and one fort closes in the afternoon, so the day couldn't slide back too far. That kind of back-and-forth is what makes it feel like planning with a friend who did all the research.

Step 3: Let Claude catch the small stuff

This is where Claude really earned its keep. It flagged details I never would have thought about until it was too late:

Bring cash. Some of the small local restaurants don't take cards.
Pack light for the small plane. The island flight has a tight bag weight limit, so I'd need a separate overnight bag.
Use the right bug spray. The bioluminescent bay requires a specific type of repellent to protect the water.
Dress for the activity. Long pants and closed-toe shoes for horseback riding, water shoes for the rainforest trails.
Protect your camera. Lenses fog up in the humid rainforest, so bring a microfiber cloth and a waterproof pouch.
Check the hours. Claude noted which spots close early or have different weekend hours, and which restaurants are small enough that you should book ahead.

Any one of these could have ruined a day. Claude caught them all before we left.

Step 4: Turn it into a checklist and a trip booklet

A list buried in a chat isn't very useful when you're actually packing. So I asked Claude to make it interactive.

An interactive checklist. Claude built a simple checklist page, styled like Apple Notes, with everything I needed to pack and book. I can tap items off on my phone, a progress bar shows how close I am, and it remembers what I've checked off. It also included reminders like calling ahead to confirm restaurant hours.

A printable trip booklet. Then I asked for something I could keep offline. Claude made a small booklet sized to fold in half, with:

A cover with our trip dates
A week-at-a-glance overview, plus where we're staying and our flights
One page per day with the schedule and a "good to know" tips box
A bookings and contacts page with phone numbers and blank lines to write in confirmation numbers
The packing list

Having everything on paper is a lifesaver when your phone has no signal on an island.

Step 5: Keep the trip on budget

The fun part of a trip is easy to plan. Staying on budget takes a little more discipline. Here's how Claude helps me with that side:

One yearly travel budget. I set my travel budget by the year instead of by the month, with rollover. That way a big trip draws from money I've set aside over time instead of blowing up one month's budget. Claude helped me set this up after reviewing my spending in Monarch.
Use your card's travel perks. My credit card has travel credits that apply automatically, and some hotel credits that only work when booking through the card's travel portal. Claude reminded me to check those before booking anything.
Track friends' share of costs. When friends pay me back for shared costs like a rental, I make sure it counts against my travel spending instead of showing up as income. That keeps my real travel cost accurate.
Plan the splurges. Having the full itinerary upfront made it easy to see which days were expensive and which were cheap, so there were no surprises.

Tips for planning your own trip with Claude

Give it your style, not just your destination. Tell it your pace, budget level, and must-dos. The more context, the better the plan.
Push back. If a day feels rushed or starts too early, say so. Claude will rework it and explain any trade-offs.
Ask it to double-check hours and rules. Opening times, closing days, and activity requirements change. Ask Claude to look up the latest info.
Ask for formats you'll actually use. A checklist you can tap on your phone and a printed booklet beat a long chat you'll never scroll back through.
Plan the budget with the trip. Decide what you'll spend before you book, not after.

Final thoughts

At the end of the day, Claude didn't replace the fun of planning a trip. It replaced the stressful parts: the endless tabs, the forgotten details, and the last-minute panic. I spent less time organizing and more time looking forward to the trip. If you've got a trip coming up, give it a try. You can do it too!
