Deborah, I'm afraid if it's night life you are after you going to the wrong place. Night life in Mastihari revolves around the dozen or so excellent Tavernas and three or four relaxing bars. On the plus side you couldn't be taking your daughters to a safer place. The Achilles Hotel is a mile or so outside the main resort which you can reach along a paved footpath at the back of the beach, there are lights along the path but not all of them are in working order. For night life you can take a 15 min taxi ride to Kardamena and for shops you could jump on a bus and go in to Kos town, the bus service is good and cheap. Hope you have a good time. If you do go in to Mastihari visit Yiannis at the half time pool bar. Great guy, excellent clean pool, no problems with the sun beds when we were there in late September though I would agree a bit of weeding wouldn't go a miss although it all adds to the charm.
