4The Lover’s Deep Submarine Hotel – Caribbean Sea

Price per night: $175,000. Perhaps the most unique accommodation on this list, the Lover’s Deep Submarine Hotel is not your typical suite. Operated by Luxury Submarine, it offers an ultra-exclusive underwater experience with a crewed personal submarine stationed in the Caribbean.

This hotel literally submerges guests in luxury. With a private chef, personal butler, and underwater views of marine life, it’s an intimate and adventurous experience reserved for those who have truly done everything else. Billionaires looking for privacy with a twist of aquatic novelty are the primary clientele.
