Mikey - keep all your text as to West Penwith, add the Minnack and Lamorna and through to Jelberts.....eliminate Lands End, that could be used for some bombing practice for what they have done there, thanks to Peter de Savary who started the ruination. Thank God he didn't mess up Falmouth or Charlestown. As to keeping Penzance or Newquay, I'd opt for the former.
information - Mousehole may be a very good place for her to go, not that far from Penzance station and a lovely chocolate-box fishing village, famous for its Stargazy pie and also, tragically, one of the worst RNLI accidents.
Look at the Old Coastguard Hotel or the Ship Inn (the latter probably cheaper and on the harbour front)....great bistro behind it in No2 Fore Street....bright, airy, really good fish and reasonably priced for the quality that you get.
And Jelberts - the best Cornish ice cream around and been there since I was little and beyond.....now owned by the Glover family, Helen of Olympic 1st gold medal fame.
