Jonathan -
I visited at least one of Rick's choices when in Dingle last year and was not impressed, by any means. We ended up at Greenmount, which may have also been one of his alternate suggestions - nice place.
I do not recall the other B&B's he recommends - but I would suggest Emlagh Lodge (owned by Maggie Flaherty). We're renting Maggie's self-cater cottage in a couple of weeks - the Emlagh Cottage (neither to be confused with Emlagh House, also in Dingle).
Emlagh Lodge is on the Harbor - and is a short walk along the Harbor into Dingle town. We saw it when were there and thought it would be our first choice if we went back. Who'd of thought it would be so soon . . .
