We have spent a lot of time in Spain over the years, before Brexit often for6 months at a time. If you avoid the tourist areas such as Barcelona, Benidorm etc it is fine. Unfortunately the Brits behave so badly it has given us all a bad name. Inland Spain is lovely as is Northern Spain albeit the weather is not so hot as the Costas. Try to integrate and learn some Spanish and they will greet you with open arms.
No, the British don’t behave badly. Some British behave badly, so do some Germans, some Dutch, some Russians and some of all other nationalities.
We have never been to Benidorm or Torremolinus, nor any other over populated resort. We never stay in ‘resorts’ where everything is provided and you don’t need to leave the grounds. We find little privately owned rentals and explore places that are not rammed with tourists. I’m afraid though, that if tourism is to be discouraged or even stopped, then the locals will be the poorer for it. Tourism brings enormous financial benefits and everyone is richer for it. Spain was dirt poor before it embraced tourism and the EU.
We prefer Greece to Spain anyway, although we did visit Seville recently. The many restaurants were full. How many would fail without the tourists? Perhaps the Spanish prefer unemployment to tourism.
No, we wouldn’t visit the Canaries or Balearics at the present time because we would clearly be unwelcome.


Not dignified imo
