Known as "the world's first electric livable yacht," The Arkup in Miami is a modern, sustainable floating mansion, with four bedrooms, four-and-a-half bathrooms, and fabulous panoramic views with floor-to-ceiling windows, and glass walls on the deck that never hinder the view. Rent space in the Miami one on Planet of Hotels. Prices vary depending on dates (approximately $2,000 per night), with an additional fee to get it out on the water.
