Plans for a major redevelopment of the four-star Dingle Skellig Hotel are being appealed to An Bord Pleanála.
Objections centre around what effect a four-storey high extension will have on sea views along the main approach to the West Kerry town.
The plans were approved by Kerry County Council in recent weeks.
The plans for the extension to the Dingle Skellig are part three-storey and part four-storey, up to 1,510sq m for 32 bedrooms. The sea-front restaurant is also to be extended by 132sq m. There is also an extension planned for the reception area and new car park will be created in a field across the narrow road linking to the N86.
