If you fancy a night sleeping under the sea, here's your chance. Oliver's Travels, a company which offers quirky and interesting vacations, has just the right holiday for you. Its latest venture is a leisure submarine hotel which can take you into the depths of the ocean for a truly unique experience. The interiors and furnishings can be customised to suit different tastes.
The submarine - named Lovers Deep - is designed with the romantic couple in mind. The company offers free rose petal-scattering services, and there's a special aphrodisiac tasting menu for adventurous travellers who want to join the "mile-low club". For honeymooners, the menu is free.
A night on the vessel starts at £175,000 (HK$2.27 million).
