It's fairly straightforward getting into YBTL. There's a lot of military airspace around, but good easily followable VFR corridors S & N.
The southern one starts around Giru, tracks between the coast and the hills and in.
Radio quite straightforward - ATIS, approach for an airways clearance, passed to tower etc.
Not sure about parking, but shouldn't be a problem I would think. Pick your time for when there's no cyclones lurking obviously!
