Switzerland the week after Christmas

I have found that the meal plans offered by Swiss hotels in the ski resorts are a very good value. You are unlikely to find anything cheaper going out to other restaurants and the food probably will not be any better, just more choice. The hotel will have a set menu every night with just a couple of entre choices (meat, fish, or vegi) but it takes a lot of stress out of deciding where and what to eat every night. At least one night is bound to be either raclette or fondue.
As for skiing, there is nothing wrong with staying in Lauterbrunnen, especially the week after Christmas which is super prime time with most hotels requiring a minimum 7 night stay with meal plan at their highest rates of the season. It will just be a bit longer commute to the slopes every day. The valley doesn't get much sunlight that time of year, but prices will be a lot higher in the more desirable locales like Muerren or Wengen. One advantage is that if you get multiday lift passes for the entire region, the ride up to the top of the Schilthorn is included in your ski pass. If you want to go to the Jungfraujoch, your ski pass will get you as far as Klein Scheidegg for free and you only need to pay the fare above that location. The ski pass will also get you into Interlaken to visit there. Also, don't forget sledging (sledding) as an activity. I'd say there are a lot more things to do in the Lauterbrunnen valley than Adelboden. I'd me more inclined to go to Adelboden if skiing was all I wanted to do (for less $ than the big name resorts).

Thank you for the information.
Also, if everyone in our group is not a skier, do you have anywhere that you might suggest (Interlaken or Lucerne or ?) where one might be able to take a train from to ski or take a train just for the day to a smaller town/village?
I have never been to Switzerland and would love to see (and , if possible, stay) in the Alps. And , again, our daughter is traveling by train from Freiburg, Germany and we are flying in to Zurich and are looking for a good town to meet up in. Or, maybe we should stay in a couple of towns? Any ideas?
Thank you for responding.

For non-skiers, the Berner Oberland also offers plenty of winter hiking and sledding trails, more than I've seen in many other comparable resorts. These are usually narrower trails of tightly packed snow that often parallel and cross the ski pistes. I'm a skier, my wife isn't, but we both (and our dog) had a really fun day sledding down from Kleine Scheidegg to Grindelwald.

Speaking of Grindelwald... if you can find a hotel that allows you to book a shorter stay, this may be a preferable location for your group. It offers much easier access to the Männlichen, Kleine Scheidegg and Grindelwald First ski/sledding areas, and it you ask me, the First area is the best of the four major ski areas in the region. As pretty as Mürren is, I wasn't very impressed with the skiing on that side of the valley, and Lauterbrunnen is the least convenient of all the towns (except perhaps Interlaken).

I also agree with lauterbrunnen from a logistics point of view, as there are lots of transportation options from there and other things to do for those that aren't skiers. The responses in this thread are good and should point you in the right direction.
