No experience, but EBCI doesn't seem an attractive destination to me. It is an active base for Ryanair and is busy developing other commercial pax traffic. There have been shortages of tower staff, leading to suspension of service for non-commercial traffic.
If you really want to use that aerodrome, best indeed to get in touch with the flying schools. But if you can, use an alternative: EBSH Saint Hubert (sic!*) is not so very near but is beautifully located in the Ardennes forests; nearer are EBSG Saint Ghislain, EBNM Namur, EBCF Cerfontaine. EBSG boasts a hard runway, though not very long, it also used to have a very good restaurant. Or, if you are into Brussels, perhaps consider EBGB Grimbergen, a very nice place though it has its limitations.
* I keep on wondering how strong the Brits are at misspelling nouns proper, especially outside their own domain.
