Sydney, Australia

With an exchange rate of around 75 cents to $1 Australian dollar, the country’s largest and most famous city is much easier on the wallet than it's been in recent years. For example: The Sydney Harbour BridgeClimb adventure, which gives you a thrilling bird’s eye view of the Opera House and harbor, is priced at $158 Australian dollars — meaning it will only cost American cruisers about $117.
