Chris, I agree. I think things can change but it would be good if it is done with a bit of thought.
We used to stay in a lovely old Spanish Pension. It was white with green shutters. Then they decided to modernise it. They put aluminium window frames in and cladded the outside and ruined it. I recon they could have spent the same amount to improve the place, still preserving the original look.
And anyway, I would prefer if they didn't attract more Brits......
