Playa Del Remolino

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.

It seems there may have been either a mix-up with the location's name or an imaginary setting was presented. Spanish coastal regions, famous for their beautiful beaches, include the Costa del Sol, Costa Blanca, and the islands of Mallorca and Ibiza, among others, where descriptions similar to what you've asked for can accurately apply.

For an exercise in imagination based on a hypothetical beach scenario or for information about actual coastal beaches in Spain with rich amenities and nearby facilities, I'm here to help. Please clarify or provide a different setting for the description you seek.
