it is clear from previous posts that there is no avoiding the valet parking at the GW.
as Australians we find the valet parking thing very strange. as well as tipping of course. you have to grow up with these things I think.
anyway, is there anywhere reasonably nearby where we can just park the rental car and walk to and from the hotel? is it safe to leave the car around (no point escaping valet parking if car is damaged by someone else!)
