The Abraj Kudai, which is owned by Saudi Arabia's Ministry of Finance, will feature 12 towers, 10,000 rooms, and upwards of 70 restaurants. That's more dining options than many towns have.
Entire floors of this 1.4 million square meter complex are to be dedicated to royal guests, and helipads will be added to sections of its roof. And there will be a full-size convention centerinside the hotel.
Aside from becoming the largest hotel in the world by room count, Abraj Kudai would also house one of the world's largest domes atop its tallest tower.
London-based Areen Hospitality is designing the interiors, which is quite the task given the opulent attention to detail on the exterior.
The hotel is planned to open in 2017, but national economic issues may delay the project to 2018. Either way, there's plenty of time to start saving for a stay in one of the hotel's five-star towers.
