The Regional-Pass does indeed provide 5 days of free travel, but the expensive routes (such as Jungfraujoch and Schilthorn) are still only 50% off. So you will pay the same as you will with the Half Fare Card you already have. The "free" routes are the less expensive routes so the cost savings is highly unlikely to add up to the price of the Pass. You are mainly buying 5 days of "hop on hop off" during your 14 day holiday. I think that is quite a premium to pay for this convenience, but of course only you can decide! I have been to Wengen 15 times and traveled all over the region. I have never waited in line longer than 10 minutes to buy a train ticket. If you are going to multiple places in a single day (which is likely in this region of so much to see and do) you can buy all of your tickets at the same time -- train, bus, boat, lift, gondola, etc. -- from the same ticket window. In other words, when you leave Wengen in the morning, tell the train staff at the ticket window everywhere you plan to go that day and you can get all the tickets at the same time. Tickets are good for the entire day, not for a specific train, bus, etc. so you don't have to work out your timing in advance.
The Jungfrau Railways Pass is good for 6 days and it includes the Schilthorn but still does not include the expensive trip up the Jungfraujoch.
Ao, as Arno suggests, look at these two cards and figure out if the price you will pay is worth the convenience.
I always just stick with the Half Fare card as I have found it provides the best value for the money.
