Parkside Inn Motel & Conference Centre, 1043-1049 Plenty Rd, Kingsbury VIC.
https://www.parksideinn.com.au/Posted for those (Bodo, Dougie, may be some others) looking for budget accommodation, only around 30min NW of the City. Not far from where you guys stayed last visits.
Haven't stayed, can't comment on the standard of accommodation, but at the price, some short-comings (if any), it may be worth the risk. Booking sites indicate from around $115 per night, but the sign out the front indicates better.
The sign was there today.
