P FENTON, of Galmpton, Salcombe, writes: Where did the 'magic ­number' 56 banded about as being the minimum amount of rooms required to make a hotel viable come from? I know a delightful family-owned hotel not far from here with fewer than half that number and yet it is doing very nicely, thank you. Is the public so dim-witted it has to fall for everything that appears in print? Look at the numbers given for the new housing sites. Perhaps you get the drift.
