It depends. An air-con room can bring the sniffles along with cold air. Fan rooms are generally better ventilated and have easily opened windows -- often preferable in a beach hut. Cheaper air-con rooms in particular can be grimy and stuffy, often with air-con that doesn't actually work very well or is very noisy. If you can't open the windows and there is a blackout, they can be downright unpleasant.
On the other hand, if you're travelling in the steamy heat of March to May and you haven't acclimatised or you find it difficult to function in hot weather, air-con can be invaluable and worth the extra couple of dollars. Another issue with fan rooms is that by leaving the windows open at night you open yourself to the risk of theft.
