..


can anyone explain why they are
booked solid in April? What type of conditions should I expect the
first week of June?

April to June is the best time
Just like most pilots from northern countries, they like an early
start.
When I was there in, April 21/07, The team from Denmark and others
were getting ready for the season and the EU championship.

There are 2 bottle necks, one, there are two groups, about 10 pilots
each that take a course of mountain flying and most if not all book
rooms. the second bottle neck is, pilots that rent rooms or bungalows
but bring there own gliders. Some book into hotels locally, which I
would do if I were to do it again, much more civilized.

If you want a course for Mountain flying in the period from April to
June book early, about six month ahead of time.

I do not think you will have any problem dropping by and getting a
couple of sight seeing flights on short notice.
