Stayed at the Adelaide Hilton for a night this week, originally given a standard room but was upgraded to an executive floor room (which gives lounge access) once I reminded them of my gold status (staff were very apologetic). Lounge is great, with attentive staff, free drinks in the evening and buffet breakfast. Anyone with status staying there should request an executive floor room as they are far nicer than the standard rooms (based on the 5 minutes I spent in the latter).
