I didnt say being in schengen would be enough except the case of UK .
I thought that you had said exactly that.
So what you are saying is that instead of Russian Oligarchs, it is now Polish "Oligarchs" bringing their dollars to Turkey? :)
Nothing will make up for them. But many middle class Russians will choose Sochi over Turkey, because Rubel's lose of value.
Ireland has a common travel area with the UK and is therefore not a full member of Schengen. Schengenvisas do not apply to Ireland.
Perhaps. I've never been there.
