Switzerland, Bernese Oberland hiking

Hi,   This is my first time trying to organize something like this. 

I have committed to a vacation in The Bernese Oberland/Alps area of Switzerland.  I'm looking for others to join.   Ideally, it would be 6-8 people sharing the cost of a Holiday apartment with 3-4 bedrooms as needed.  Base Location would be Grindelwald for 7 nights then Lucerne for last night. Day hikes around the area with possible visits to Murren, Gimmelwald, Kleine Scheidegg, The Jungfrau.   In the valley, there's Interlaken and Brienz both on lakes. Many adventure activities in the area:  Tandem Hang gliding, canyon jumping, paragliding, skydiving, flyfishing, jetboating to mention a few.

 Here's a couple of links to get you excited.

I have no planned group itinerary beyond this.  I like flexibility when I travel but we can all meet up nightly to discuss our options for the day/days ahead.    A communal $ pool for breakfast supplies might be a good idea.

I estimate cost based on 6 participants to be $2350/person including roundtrip nonstop air from Boston to Zurich, 4 days of train travel in the time period we're gone (swiss flexi pass), loding for 8 nights.  Price could drop if we have 8 and cost is recalculated.   People from other areas are welcomed to join.

Hit me up with any questions.
