Well I usually post a question like this on PPRuNe as part of preflight preperations when going to somewhere slightly off the beaten track in Europe (not that Salerno is particularly...)
Just to get a feel for any local quirks, things to look out for, commonly used local but perhaps unofficial proceedures, issues people have had in the past with airport officials, etc. Stuff that might be useful that doesn't appear in the AIP or wouldn't necessarily gained by emailing or ringing someone up who might not have the best grasp of English.
All entirely supplementary of course to normal flight planning process...
