Question
How do I plan a 7-day Europe trip with minimal transfers, predictable costs, and only a carry-on?
Tools
- Transport search: Trainline (aggregates SNCF/DB/NS), Omio, Google Flights.
- Fare checks: DB and SNCF direct sites for saver fares.
- Packing rules: TripPlugin Packing Rules.
- Plug types & SIM: TripPlugin Plug Checker and SIM Tool.
Solution (process)
- Pick 3 hubs within 4–6 hour rail hops (reduce transit time).
- Book trains 30–60 days out; saver fares can be 40–60% cheaper.
- Use contactless/Apple Pay for metros; skip paper tickets.
- Pack to 7–10 kg; avoid low-cost carrier luggage fees.
Example: Paris → Amsterdam → Berlin (7 days)
- Day 1–2 Paris: Stay near Châtelet for RER/metro access. Metro single €2.15 (Jan 2025). Museum timeslot tickets required for Louvre.
- Train to Amsterdam: Thalys/Eurostar 3h20; advance fares often €45–€95 (Trainline data Jan 2025). Verify if fare bands change.
- Day 3–4 Amsterdam: Use GVB 1-day ticket €9; bike rental €10–€15/day.
- Train to Berlin: ICE 6h20; saver fares €39–€69 when booked ~30 days out (DB site).
- Day 5–7 Berlin: AB 24-hour ticket €9.90; museums on Museum Island €12–€19 each—book online.
- Budget (excluding flights/hotels): Transit/activities €170–€230 per person for the week.
Packing list (carry-on, 7–10 kg)
- 5 tops, 3 bottoms, 1 mid-layer, 1 rain shell.
- Comfortable shoes + packable slip-ons for hotels.
- Universal adapter + surge protection (see gear picks).
- 1L toiletry kit (100 ml containers); solids where possible.
- Offline maps + transit apps downloaded.
Recommendation summary
- Choose three cities with direct trains; avoid same-day flight hops.
- Book rail 30–60 days out; check both aggregator and rail operator for the lowest fare.
- Travel carry-on only to dodge €30–€70 low-cost baggage fees.
- Use contactless in metros; no need for paper tickets in most EU capitals.
