Coming in at $170 per day on Price of Travel's 2014 Three-Star Traveler Index for budget travelers, Copenhagen is pricey even if your vacation desires are modest. TripAdvisor's TripIndex ranks Copenhagen among the 10 most expensive international cities for a vacation, putting the cost of a night at a nice hotel, taxi, and dinner and cocktails for two at around $440.
That said, there are definitely ways to maximize your vacation budget. For instance, the Copenhagen Card cuts costs on attractions and transportation. And unlike many city cards, this one allows you to easily calculate how much you're likely to save before you purchase it. The calculator on the right side of the page lets you mark which sites you're likely to visit to compare the cost of the card against the a la carte pricing of individual attractions. And Copenhagen's many inexpensive bicycle-rental companies allow you to experience the world's top cycling nation from the back of a bike.
If You Want to Save: Don't tip for services. In Denmark, gratuities are built into the price you see, so unless you experienced service that was so above and beyond that you think it deserves additional monetary acknowledgement, don't add extra money to your bill.
