Lover’s Deep

With the launch of a luxury submarine that plumbs the depths of the ocean and comes with soundproof chambers and a private chef, adventurous couples who have already been inducted into the Mile High Club may now take their love to a new level. The Lover’s Deep - one of the most expensive hotels, an underwater hotel can be found near a coral reef off the coast of St. Lucia or near a sunken battleship in the Red Sea.

However, love at the bottom of the sea isn't inexpensive. To board the submersible vessel. A captain, private chef and butler, speedboat transfers, and optional add-ons such as helicopter transfers, beach landing, two-person shower, and champagne-soaked breakfast are all available.

Furthermore, in Lover’s Deep, you have the ability to tailor the cruise to your personal interests, so if you prefer one place over another, the captain will obey your wishes. Staying in the world's most costly hotel would be a once-in-a-lifetime event that you'd never forget!
