Oliver,
There are no pitfalls as such that spring to mind. Are you using the Jepp Airfield plates? There are a number of defined VFR arrival / departure routes which are used almost without exception. I seem to recall a notice earlier in the year that handling was mandatory for visiting aircraft. Best bet is to give the guys at Air Service Limburg (ASL) a call for the current gen. Telephone number is +31 43 3646949. Otherwise, the field is pretty straight forward.
Enjoy the trip. I just hope the wx improves from what it's at at the moment.
If there's anything else you think I can help out with, just ask.
