The Johnson Collection here is indeed worth your visit.
3) Sydney: I stayed for three days, and the overall feeling is average, except for a zoo that aroused my son's keen interest (the name is forgotten, the largest in the area), the Blue Mountains are even more average, and the Sydney Opera House feels like a scenic spot similar to the Great Wall. Take a look. That's it. Live in Radisson hotel, closed to China Town & Darling Harbour. $140/day
