I'm sorry, but it seems there's been a confusion. Playa Del Remolino, as described within the context of your inquiry, does not align with known beaches in Spain. Fresnillo de las Dueñas, which you've mentioned, is located in the Burgos province and is not coastal, thereby not having beaches such as those found along Spain's extensive coastline. The characteristics you're seeking to hear about, including parking, fun facts, attractions, restaurants, hotels, and specific beach amenities like lifeguards, bathroom access, and policies about dogs, relate to typical beach settings. However, given the location you've mentioned is inland, these details do not apply.
