Thanks!
Firstly, thank you for all the help and advice!
We have now decided to visit Maastricht airfield and then drive to the nearest christmas market. We will be flying out on Friday the 4th of December and returning the next day, so fingers crossed for good weather!
Finally, just to pick he brains of locals and those who have visited Maastricht before, are there any pit-falls or local procedures that we should be aware of to try and make the trip as stress-free as possible??
Oh and as for the offers of drinking companions, we may take you up on those at a later date! =-)
Cheers, ollie.
