There are a lot of things that can make your stay at a hotel expensive. The history of the building, its proximity to popular tourist destinations, or even how recently it received a redesign — hotel designers know how to get you to pay premium prices.

Occasionally, though, a hotel is expensive to stay in because it took a lot of money to build. Here are the most expensive hotels ever built.

Among the towers that make up the most expensive hotel in Macau, and all of China are Hard Rock Hotel, the Grand Hyatt Macau, and the Crown Towes Hotel.

The Wynn Resort spreads over 600 acres of land and is the sixth largest hotel in the world. It was constructed in 2005 at a cost of $2.7 billion.

For example, the Wynn Resort became the first casino in the Las Vegas area to feature a car dealership.

There are currently plans to add another 35 acres to the resort with the construction of the Wynn Paradise Park, slated to be completed in 2020 for an additional $1.5 billion.
