I agree GG - Marbella and very specifically Puerto Banus which from what I read seems to attract gangsters these days, I find those areas of Spain very unappealing. I did go to Benidorm when I was a teenager with,
no taste I think, or at least I hope, I have acquired some since. Seville, Cordoba, Granada and San Sebastian all wonderful.
Oban - I don't think it's a city, went there at the height of summer, tantamount to a nuclear winter, perpetual driving rain, freezing cold, didn't bring our winter clothes, just grey and miserable.
Whilst I love France, every time I've been to Paris, I've found it extremely underwhelming. I prefer France's smaller more provincial cities, Blois, Aix en Provence, Avignon all spring to mind.
