My Swiss itinerary. HELP! Basel/Geneva/Bern???

Hi all,
I'm planning a trip to Europe next spring (end of April/early May) and will visit Switzerland around 3-4 days.
Here are my route plans:

PLAN A
Day 1: BRUSSELS (flight)-GENEVA-LUCERNE
Day 2: LUCERNE (Lake Brienz)-INTERLAKEN-LAUTERBRUNNEN
Day 3: LAUTERBRUNNEN (sightseeing LAUTERBRUNNEN-WENGEN-MURREN)
Day 4: LAUTERBRUNNEN-INTERLAKEN (transit)-BERN/BASEL (choose either one)-PARIS

PLAN B

Day 1: BRUSSELS (flight)-GENEVA-LUCERNE (Lake Brienz)-INTERLAKEN-LAUTERBRUNNEN
Day 2: LAUTERBRUNNEN (sightseeing LAUTERBRUNNEN-WENGEN-MURREN)
Day 3: LAUTERBRUNNEN-INTERLAKEN (transit)-BERN/BASEL (choose either one)-PARIS

PLAN C
Day 1: BRUSSELS (flight)-GENEVA-INTERLAKEN-LAUTERBRUNNEN
Day 2: LAUTERBRUNNEN (sightseeing LAUTERBRUNNEN-WENGEN-MURREN)
DAY 3: LAUTERBRUNNEN-INTERLAKEN (Lake Brienz)-LUCERNE-BERN/BASEL (choose either one)-PARIS

PLAN D
Day 1: BRUSSELS (flight)-BASEL-LUCERNE (Lake Brienz)-INTERLAKEN-LAUTERBRUNNEN
Day 2: LAUTERBRUNNEN (sightseeing LAUTERBRUNNEN-WENGEN-MURREN)
Day 3: LAUTERBRUNNEN-INTERLAKEN (transit)-BERN/GENEVA (choose either one)-PARIS

*The one that I mark *choose either one* is because time is limited so I might cannot visit both places

1) Which plan do you think the best and why?
2) Between Geneva and Basel, which one is worth-visiting and why?
3) Between Bern and Basel, which one should I pay a visit and why?
4) Between Geneva and Bern, which one would you recommend for a visit and why?
5) Do comments on my itinerary. Advice and ideas are much appreciated as this is my first visit to Switzerland.

Thank you.

Hi syuonthedot. If you manage, a 4 day trip would be nicer than a 3 day variant, simply as it provides more time for sightseeing. Since time is limited in all of your options, I'd advise not to include Geneva, as that requires quite some traveling time to the Lucerne and Interlaken regions that seem to be your main focus. You'd better enter and depart from Zurich and/or Basel. If you like a city visit, I think Bern would be more appealing than Basel. But as Arno already mentioned in your previous topic: if weather is good, you may want to spend as much time as possible exploring the mountains instead of towns.

Hi,
Thanks for your reply.

However, I've changed my route plan and narrow down to two choices. as per below.

PLAN A
Day 1: PARIS (train)-BERN (choose either one)-INTERLAKEN-LAUTERBRUNNEN
Day 2: LAUTERBRUNNEN
Day 3: LAUTERBRUNNEN-INTERLAKEN (Lake Brienz)-LUCERNE (Chapal Bridge, Lion Monument, Lake Brienz)-BASEL-MANCHESTER (flight: 5pm)

PLAN B
Day 1: PARIS (train)-BASEL (transit only if time is limited)-LUCERNE (Chapal Bridge, Lion Monument, Lake Brienz)-INTERLAKEN-LAUTERBRUNNEN
Day 2: LAUTERBRUNNEN
Day 3: LAUTERBRUNNEN-INTERLAKEN-GENEVA-LIVERPOOL (flight: 5pm)

I have checked with Easyjet and found that there is flight BASEL-MANCHESTER and GENEVA-LIVERPOOL. I would love to visit Swiss around 4 days or more but time is limited as I'll be visiting other parts of Europe to.

1) Which plan do you think the best and why?
2) Between Day 3 (PLAN A) and Day 1 (PLAN B), which one is pack and time is limited?

Thank you very much for your help and advice.

Hi again! In that case I guess plan A is a bit better, since it doesn't involve a long rail trip to Geneva. I don't quite understand your second question.
