That's about what I normally pay in Sydney. I think we got a "deal" once. At one of the Pacific International Apartments in Chinatown. It was about $375 for 2 nights; with a playstation thrown in for a studio room.
Last time I stayed overnight in Sydney, it was to attend a wedding in Double Bay. We stayed at one of the hotels there...must have paid about $200 per night. No kids invited; so DH and I thought we'd have the weekend to ourselves. We flew out on a Thursday night....right bang smack into a thunderstorm at Sydney airports. We were supposed to have gotten to our hotel by 8.30 pm. We touched down at 9 pm and the plane sat on the tarmac for over 2 hours before the storm passed and we were allowed to head to the terminal. And then the mad dash for taxi's. We finally got one past 12.30 am and got to our hotel after 1 am.
At least we could call the hotel from the plane to let them know. And they were very kind...because when we finally checked in and got to our room, we'd been upgraded to a suite!
