The Aircruise Hotel seems like a super luxury trans Atlantic voyage, without the possibility of sea sickness. I have been on a conventional cruise ship before so I know it would be much better to be riding 100 feet over the waves than on them.
Designed by the Seymourpowell studio in England, the Aircruise Hotel would be built to travel long distances and is estimated to be able to go from London to New York in about 37 hours. Unfortunately I don’t think you can use your Air Miles.
