Bored of making out on a plane at 35,000 feet? Adventurous couples who’ve already inducted themselves into the Mile High Club can now take their love to a new level, with the launch of a luxury submarine that plumbs the depths of the ocean and comes with soundproof rooms and a private chef — welcome to the Mile Low Club.

The luxury submarine is now offering a new romantic subaquatic escape, providing couples with a once-in-a-lifetime experience gift for couples that redefines underwater romance. The underwater hotel called “Lovers Deep” can be moored near the coastal reef off the coast of St. Lucia or near a sunken battleship in the Red Sea.

But love at the bottom of the ocean doesn’t come cheap. You’ll need to cough up £175,000 per night in order to board the submarine vessel.
