Say you're traveling to Germany and you need an ultra-secure hotel room (perhaps you're carrying valuable trade secrets, such as a new formula for Coke, the secret batter recipe for KFC or the special sauce ingredients for McDonald's Big Mac). Or maybe you travel with a large entourage and private staff, and you want them close by. That's no problem when you stay in the Presidential Suite at the Hotel Adlon Kempinski Berlin. The suite, located in a new Security Wing, is adjoined with other suites and rooms, while a special lounge accommodates chauffeurs and bodyguards. Two private elevators link directly to an underground parking lot. And to make you feel really safe, the suite offers a telecommunications system independent of the building, a dedicated security hub with video monitoring, bulletproof walls and windows, and a self-sufficient power supply.

It also has some soft touches: a Finnish sauna, a massage/fitness area, a private safe room, and a kitchen for the butler. In case you're not traveling with your own butler, the hotel provides 24-hour butler service, limousine service with up to five cars, an open bar and a gourmet breakfast. Plus, you get a terrific view of Potsdamer Platz. The price tag? More than $25,000 a night—but good security can be priceless.
