Poshest Irish island?

Of the 500+ islands off the coast of Ireland some are obviously posher than others. Most don't have anyone living on them which makes them a bit harder to be posh. Although not impossible

Inish Turk Beg seems quite posh

So does Inisheer. It might not have the million dolla 'pad' but houses aint cheap there. A sizeable barge used to call there, courtesy of Irish water keeping the tanks topped up. Everyone there seems to be on holidays. Well-to-do teachers trying to pass the 3 months, people with holiday homes. Much of the banal everyday working life seems to be blisfully absent from this island.

Then there's Rathlin. Full of day trippers sitting on the terrace with their pints waiting for their meal to come out. But which is the poshest? Phone now to get your vote in early.. 1550 915 ...
