I Prague there is just one international airport Ruzyn?...
if there wont be too much competitors from countries so far I could give a lift by car... in other case it is not so far... just travel by bus to metro, then 10 stops by metro and you will be at meeting point... how to get there I will write on sites till end of the July...
public transport in Prague is very simple... just 3 lines of metro which you can use for transport almost everywhere...
For competitors there isnt free accomodation but hotel rooms will be managed and booked for them... you have to pay it yourself...
I am prepared for any other questions :biggrin:
