Suitable airports Belgium/France/Germany for helicopter night training

Hello,

For next week I need to find some airports where I can do some night training. I already called a number of German (controlled) airports, however, they allow night training but they close at 9 or 10 pm. In summer it is not possible to do night training with these closing hours.

I am training for my CPL together with another student in an R44 helicopter, so we need to fly 10 hours night in total (VFR). We are planning a trip of 4 days (3 nights) to do the last part of our navigation training and night training.

The only airfield I found where it is possible to continue throughout the night is LFAT.

Suggestions for suitable 24H airports (with a reasonable landing fee) are welcome :). Preferably with a hotel close to the field.

Thanks in advance
