The castle, built to resemble "a modern mansion," is located in Coney Island at the southern tip of Brooklyn. The stay includes dinner for two on the Coney Island Boardwalk (sounds nice, but it could really go either way), sunrise beach yoga, and VIP passes to the small but mighty Luna Park theme park.
The structure is eight feet tall and 18 feet long and wide and absolutely covered in branding. So, it's tiny for a house, massive for a sandcastle, and says "booking" more times than the actual Booking.com website. It'll run you $29 per night to get the reservation, but you're going to have to show off your nimble fingers. You can book starting August 22 at 12pm for a two-night stay on August 23 and 24. So, very few people are going to be able to get in on the stay.
And, because you're wondering if this will end in tragedy, the images look like there's a structure under the sand to stop it from falling in on you. A representative also confirmed that the base of the structure is made of plywood. Additionally, there aren't images of it, but a representative confirmed there's a private bathroom with a toilet and shower. You aren't going to be trekking across the beach at night for a porta-potty.
