Take one of those plug in thingys for repelling mozzies in the room, we spent our first night in May swotting the little so and so's! Next day bought a Mr Fist plug in and tablets from Vavilas(?) market, just opposite road to San Stef, and no problems in room after that.
There is a quiz night on Friday and Sunday nights at Thomas Bay hotel in San Stef. During our week we won them both.... bit embarassing really,when we were staying in Arillas, and had travelled independently and not with Thomson, who organise it, but the wine we won was lovely!!!
