What if I lose access to my digital SRC?

This is why you print a one-page backup with essential info: flight confirmations, hotel addresses, emergency contacts, and insurance policy number. Keep it in your travel documents folder. The full SRC is for planning; the backup is for emergencies.

Should I use a travel planning app instead of building my own SRC?

Travel apps like TripIt automatically pull booking details from your email, which sounds convenient but creates a black box you don't control. SRC means you decide what information matters and how it's organized. Use a planning app if you want, but many travelers find a simple document more reliable and flexible.

How detailed should my SRC be?

Detailed enough that you could hand it to someone else and they could execute your trip. Include confirmation numbers, addresses, phone numbers, and links. But don't over-plan—leave room for spontaneity. The SRC is your safety net, not a rigid schedule.

Can I use my SRC for multiple trips?

Yes, but create a new SRC for each trip. Don't try to maintain one master document for all travel. Archive old SRCs—they're useful for future planning (what did we spend on food in Portugal?) but keep current trip planning clean and focused.

What about security for sensitive information?

Don't put full credit card numbers or complete passport numbers in your SRC. Put passport expiry dates and the passport number separately, maybe just the last 4 digits in the main doc. For credit cards, just note which ones you're bringing and the phone number to call if lost. Keep full details in a password manager.

How to Use SRC (Single Point of Reference) for Travel Planning

SRC (Single Point of Reference) is a travel planning method where you keep all trip information in one centralized location instead of scattered across emails, apps, and bookmarks. Choose one tool—a document, app, or notebook—and build your trip there with links, confirmations, and notes in a format you can access anywhere.

Choose Your SRC Tool. Pick exactly one place for everything. Google Docs works for most people—shareable, accessible offline, searchable. Notion if you want databases. Apple Notes if you're all-in on Apple. A physical notebook if you prefer paper. The tool matters less than committing to one.
Set Up Your Structure. Create sections before you start researching: Overview (dates, travelers, budget), Transport (flights, trains, transfers with confirmation codes), Accommodation (each booking with address and check-in details), Day-by-Day (blank outline of your itinerary), Bookings (restaurants, tours, tickets), Documents (passport copies, insurance policy, visas), and Emergency Info (embassy contacts, travel insurance number, credit card phone numbers).
Add Information As You Find It. Every time you book something, immediately add it to your SRC. Paste the confirmation email. Add the confirmation number. Include the cancellation policy if there is one. Add the address and a Google Maps link. If you're researching and find a good restaurant, put it in the SRC under the relevant day. One source of truth means you never wonder where you saved that thing.
Build Your Day-by-Day. As your trip takes shape, fill in the day-by-day section. Not a rigid schedule—just the structure. Day 1: arrive 2pm, check in Hotel Name, dinner neighborhood. Day 2: morning museum (link to tickets), afternoon walk route (map link), evening free. Enough detail that you know what you planned to do, loose enough that you can adjust.
Make It Accessible Offline. Save your SRC for offline access. Google Docs: open the doc on your phone and it caches. Notion: enable offline mode. Or export a PDF and save it to your phone. Print a copy if you want backup. The point of SRC is having it when your hotel WiFi fails or you're on a train with no service.
Share It If Traveling With Others. If you're not traveling solo, share the SRC with your travel companions. Google Docs makes this easy. Everyone can add their bookings, suggest restaurants, see the plan. One shared source beats ten separate email threads.
Update It As You Go. During the trip, update your SRC when plans change. Found a better restaurant? Add it. Decided to skip the museum? Note it. Your SRC becomes the record of what you actually did, which is useful for future trips and for remembering that amazing lunch spot three years later.
