Playmobil doesnot care Martin , sadly enough 
all those meetings mostly are organized by private persons 
Collectors like you and me 
The advantage of Europe , despite the different languages , is the distances are shorter then in the states (I Know you live in England Martin 

 )
mostly all do-able by car 
if you go dig in the meeting threats on the different fora you'll learn a lot on how those things are organized 
We even had a few playmomeets in England 
The only thing Playmobil ever did was the factoryvisits at Zindorf 
and on the first one (wich I missed) where a lot of people from round the world 
(that time there were only three fora (Spanish ,English and German)
but that also was an initiative from a Collector who had a good connection with the PR from playmobil (and she still has ) 
The beauty of those meetings is , you see more playmo then is good for you  

you meet the people behind the avatar , Lot of members here and on any other forum (regarding playmo) I met in person 
meeting in real still is different then on the net 
I'm shure a few fellow members here will agree on that 
The most interessant fairs 
Wolfsburg   Germany , THE biggest and must have seen fair in Germany 
The weekend from 18 april 2009Luxoplaymodays   Luxemburg  , where Holland/France/Germany/Malta/Belgium.... meet 
mostly end of August 
Aras   France  mostly round Mai , never been there ,project for next year  

Barcelona and Madrid  
and there are a lot more , 
The bottom line is , all these events organized and payed by Collectors who each in their way contribute to these events to become true
