Hev, As a fellow 67 owner I'll give you a tip. The official Motel has been pretty much booked out so "She who must be obeyed" suggested a B&B and we got a beauty just a walk from the action.
Do a search on Ballarat accomodation and get in early for the best deal.
You should get another motel or if you want a really nice "Bed and Brekkie", book now.
Good deals at around $120-$130/nite with brekkie chucked in. Some motels are up on this and don't have as good a setup!
There is quite a few places to choose from but remember its Easter W/E.
