rich

At least, we think that's some sort of improperly-used booze...

This is the Lover's Deep, a luxury submarine that rich people can rent to have sex in under the sea. It costs $145,000/night per person though and there's a two-night minimum, so unless you're planning on bringing a love doll for the least romantic getaway of all time, the minimum stay with another human being will set you back $580,000. I suggest going Dutch.
