I stayed in an expensive 1 (actons) when down there so dont know a hotel BUT
Make sure you go for a Meal in Man Fridays (up the hill over looking the Bay). TREMENDOUS Food and the Steak is superb!
I arrived late at Acton's hotel on one occassion and negotiated a very good price for a room. Don't get a room at the back though as it backs on to The White Lady venue that can be extremely noisy.
