Europe Trip Planner Checklist

Hi everyone!

I’m finalizing my 3-week Europe adventure and made a quick checklist.
Could you scan it and tell me what I might be forgetting?

✅ Flights booked
✅ Interrail pass ready
✅ Basic travel insurance
✅ Hostel reservations for Rome & Paris
✅ Europe Trip Planner tool -> tourspilot.com (lets you drag-&-drop cities + auto calculates train times)
❓ Best way to handle cash?

Appreciate any tips!
