4 days Swiss trip - April 2012 -suggestions please

Dear friends,

Thanks a lot first of all for posting some wonderful answers to the posts here and offering some real valuable help.
I am planning for a trip along with my family and parents to Switzerland (unfortunately for just 4 days ) from March 31 - April 3 2012. I understand that there is not much we can see but i have just worked out on visiting a few places. Here's my itenary. I really appreciate any feedback/suggestions on this:

31-Mar-12 (Saturday)
Leave from Paris to Geneva (we need to board TGV Lyria at 8:11 am from PARIS GARE DE LYON to 11:27 GENEVA CORNAVIN ). We will take another train from Geneva to interlaken West. When we reach Interlaken, we will spend time going around the town, going for boating in Lake Thun/Brienz. We can see the cuckoo clocks, watches, souvenirs here itself in the town.

1-Apr-12 (Sunday)
We will board the train from Interlaken OST railway station to Lauterbrunnen/Wengen to Jungfaujoch. We will spend the day in Jungfraujoch and then come back from Jungfraujoch to Grindelwald back to Interlaken

2-Apr-12 (Monday)
We will travel at 7 am from Interlaken to Lucerne with the Golden Pass and reach Lucerne at 9:30 am. We will check in to the hotel. We will visit the following places in Luzerne:
10:30 am - 3 pm: We will visit Transport museum (not the planetarium or the filmtheatre). From the hotel, we will take a train or bus to the museum stop - Luzern Verkehrshaus
4:12 pm - 6:41 pm: Boat trip from Luzern-Vitznau and back

3-Apr-12 (Tuesday)
Take the early morning 8:06 am train from Luzern-->Engelberg. Reach Engelberg at 8:53 am. From Engelberg, we will take the first cable car from Engelberg-->Trubsee (20 minutes), second cable car from Trubsee-->Stand (20 minutes) and then the last rotair (80-person revolving gondola) from Stand-->Mt. Titlis (5 minutes). We should reach by 10:00 or 10:30 in Mt. Titlis. We will have a stroll, see whether any snow activities are possible, take pictures, have lunch and try to come back by 4 pm or 5 pm to Lucerne. If time permits, we will see Lion Monument and Chappel Bridge in the evening in Lucerne. After that, we will check out from the hotel and take late-evening/night train to Zurich

4-Apr-12 (Wednesday)
We will depart from Zurich to Bangalore

For travelling, i am planning to go for a 4 day Swiss Pass and for my kid (he would be around 5 years 9 months) on the day of travel, i guess the STS Family card will be good. I understand that Jungfraujoch will just be 25% even with the Swiss pass and Titlis will also be 50% only with the Swiss pass.

Do you have any suggestions on which would be good ski areas for the places that we are travelling? We don't need any professional ski schooling classes but just want to have an experience with sking? Also, suggestions on paragliding and rental equipment for sking will be highly appreciated!

Look forward to your kind suggestions. Thanks a lot for your time and attention!

You will arrive at Interlaken at 14.23. If you buy your Swiss Pass (with Family card, if you like) at Geneva railway station, you will probably take a later train. Trains between Geneva and Interlaken run every 30 minutes
If you would like to arrive earlier, you would have to leave Paris Friday afternoon at 16.23.

In winter, there are no boats on Lake Thun and Lake Brienz. The spring season starts April 6th. But you can board a steamboat at Lucerne; Lake Lucerne boats run all the year round.

Cuckoo clocks are made in the Black Forest (Germany). But you can buy them in Swiss souvenir shops too, (shopkeepers import them from Germany, because tourists from overseas always ask for them).

With the Swiss Pass, adults will have to pay 75 per cent of the fare for the Wengen/Grindelwald - Jungfraujoch leg. Interlaken - Wengen resp Grindelwald is free. With the half fare card, adults pay 50 per cent for all.
Kids from 6 up to 16 years pay only if you have NO Family card. Kids younger then 6 years travel free anyway.

Go only to Jungfraujoch if the weather is fine. Otherwise you would freeze in the fog and see nothing at all.

The first train to Lucerne leaves Interlaken Ost at 7.04 and arrives at Lucerne at 9.04 (NOT 9.30), then every hour until 20.04.

If you leave Lucerne at 8.06, you will arrive at Titlis at about 9.50. The Engelberg - Titlis leg costs 50 per cent or the full fare (with Swiss Pass and Half Fare card).

The first train to Zurich airport leaves Lucerne at 4.55am (1 1/4 hrs yourney); then at 5.28, 6.10, 6.20, 6.35, 7.10, 7.20 .........

You can rent full ski equipment at Interlaken, Wengen, Grindelwald, Engelberg, etc. But I fear you will have just no time for skiing.
"We don't need any professional ski schooling classes": so I suppose you have some experience, otherwise it could get dangerous and not pleasant at all.

Check the Swiss Half fare card. I suppose it would be more advantageous than the Swiss Pass (for just Geneva - Interlaken - Zurich airport, plus Interlaken - Jungfraujoch and back and Lucerne - Titlis and back.

Dear neckervd,

Thanks a lot for your valuable suggestions. Really appreciate your help! Thanks for telling me about Lake Brienz/Lake Thun. I never knew about it. I went through a travel agent in Qatar who was giving a package for Swiss which covers Jungfrausjoch as well as giving a 5 day Swiss pass (not sure if its a flexi pass because i dont see a 5 days swiss pass).

Thanks a lot for the ski feedback. If there is no time, thats fine. Seeing the snow itself would be a treat! Thanks again!

It should be:
"If you leave Lucerne at 8.06, you will arrive at Titlis at about 9.50. The Engelberg - Titlis leg costs 50 per cent OF the full fare (with Swiss Pass and Half Fare card).
Sorry for the missprint!
