I think all guests get the credit irrespective of whether they are near the piling works or not.The restaurants are a bit pricey , but not unusually so, I think mains would be around 30-40$ ,a meal for 2( excluding drinks )would be around 100$. The issue would be variety, they have a small menu and 2 restaurants so you may get rather fed up of eating the same stuff after a few days . Breakfast is decent, but definitely not great.
