Weelde is a 'sleeping' Belgium Airforce base where gliding takes place in the weekends.
I tried flying into there a few years ago as I had done some gliding competitions there in a previous life.
No chance. Things may have changed.
Nearby Gilze Rijen (EHGR) is no better due to the unenlightened view of the Dutch Military compared to the use for civilians we have over here in the UK.
Eindhoven is OK but rather expensive.
If you need big airport facilities you can go to Antwerp which is good value or Budel (EHBD) which is smaller.
Have fun!
