Forget the Queen Mary, I want to go cruising on one of these:

Manned Cloud

The brainchild of Jean-Marie Massaud, the Manned Cloud is an airborne hotel that he hopes will change the way we view tourism.

Manned Cloud is a hotel with a capacity of 40 passengers and staffed with 15 persons, that on a 3-day cruise in 170 km/h permits man to explore the world without a trace: to re-experience travelling, timelessness and enhance the consciousness of the beauty of the world - and to experience spectacular and exotic places without being intrusive or exploitative. For me this project sums up a way of thinking that is the stake of tomorrow.

Dezeen Design Magazine has done an excellent write-up with all the details. It sounds wonderful:

Manned Cloud will have a cruising speed of 130 km/h and a top speed of 170 km/h. Two two-deck cabin will contain amenities including a restaurant, a library, a fitness suite and a spa. There will also be a sun deck on top of the double helium-filled envelopes.
