JOE: Ya have a great idea going here.
The one thing you must keep in mind is the most “cost-effective” time to travel from CONUS to Germany (via UK).
According to the airline industry the break-down of travel is as follows:
LOW
SHOULDER
HIGH
SHOULDER
HIGH
15 January
1 April
1 June
1 September
1 December
31 March
31 May
31 August
30 November
14 January
With this in mind you can see what would fit most everyone best. I have traveled to Germany almost every year and I find the best time is the shoulder period. There are less tourests, kids in Europe are still in school and the road conditions are really great.
I know that old skiiers like to gather in the winter, but in Europe you are sort-of-kinda restricted on what to do. Traveling in May or October is best because it is not really too warm, some snow is still in the mountains and prices are lower at places to stay.
Also you must keep in mind there is not much of anything left in regards to the AFRC facilities. Chiemsee is now the Club Villa and set to the new HIPPIE approach. Berchtesgaden still has the Skytop, but if you are not a member of the Golf Club, stay out. The Walker is a parking lot, Alpine Inn an Old Folks Home, Hoff sits in ruins, Stanggass Kaserne (BRA Hqs) a housing complex and the Strub with the Gebirgsjager. In Garmisch all the hotels are either torn-down or now used by the Germans. Everything is now at Artillery Kaserne (i.e. PX, Commissary, support activities, MP's, etc.). The Sheridan Kaserne (GAP Hqs) now houses The Geo Marshall Center. This used to be the old Russian Institute that was located in O'Gau years ago. The only way one can get into the EDELWEISS is with a DoD ID Card. If you have one (or a retired ID) you can have one (set of) guest/s. Talk about security. This place is harder to get into than the Fort Knox Repository.
As to the stop-over in the UK that sounds good also. During the shoulder periods the same applies there as well. London has many great low price hotels in and around Kensington Gardens.
I would venture to say if you really want to do this it will take a lot of planning in order to have places to stay and things to do as a group. I would leave the travel arrangements to each person as they will fly from the four-corners of the world. In country transportation would also be their responsibility. All you need is a time and place and THE PLAN.
Good luck and I'm with you on this.
