As someone who is British, not the drunken type. You couldn’t pay me enough to go to Benidorm. I cannot see how you can have your cake and eat it. The areas like Benidorm are actively selling this environment because they know it attracts certain types of idiots who will pay for it.
Air BnB is a plague that should be only done under license imo. I have a lot of sympathy for those who live near them. In the UK if someone is causing grief because of business being ran in populated area, then there are options to have that business removed. I would hope Spain has the same functions.
Air Bnb is causing issues in a lot of rural areas in the UK. Wales is looking seriously at the option of charging tourism taxes. This will have a big impact on those who have bought houses just to lease them as Air BnB. I personally think that any valid police call outs should be charged to the owners of Air BnB. I do not see why the community should pay the costs of policing when someone is reaping the benefits.
