I have been trying to decide, which option should I choose to go with more economically way and not able to decide. Trying to gather it since past many hours and still failing to understand it. We (2 adults) are giving very short visit to Paris and Switzerland and I would really oblige, if somebody can give some pointer and suggestion about, if we should take point to point or any pass (EURAIL Pass for France/Switzerland or Half Fare Swiss Pass, etc). My itinerary is like this :-
Day-1: Reach Paris in noon, at CDG. Leave for Lauterbrunner for night stay.
Day-2: Murren, Grutchalp, Schilthorn, Trümmelbach Fall and back to Lauterbrunnen (includes train, bus and cable car)
Day-3: Boating at Lake Brienz, Lucern city, Engelberg and come back to Lauterbrunnen by night (includes train, boat and may be cable car)
Day-4: Lake Thun, Oberhofen Castle, Bern, Basel and head back to Paris in evening.
Day-5:Full day in Paris city.
Day-6: Hotel to CDG Airport and fly out.
Here my confusion starts. We are getting cheap tickets from Paris to Geneva and back by Basel to Paris in $230 for both of us. In this case, we would not require TGV. For other days in Switzerland, larger stretches will be - (a) Geneva to Lauterbrunnen (b) Lauterbrunnen to Lucerne (c) Lucerne to Lauterbrunnen (d) Lauterbrunnen to Basel. On rest of days, out commute tickets will not be expensive. For Paris part, we will go with some single-day pass.
Should I go with point to point tickets, because our expensive most (TGV) part is already covered by flight ?
Should I go with any rail pass, only for Switzerland ?
Should I take trains only and go with two-country rail pass (France-Switzerland Eurail pass), which will give me discount in TGV trains and cover our rest of travel in Switzerland also ?
Really need help here.
