I wouldn't have wanted to have any drinks on the way to MP, as we had some light hiking planned for our first day. We saw the sights on the way, so it was not an issue to travel back to Cusco at night.
You make an excellent point. We took the train roundtrip from Ollantaytambo and for such a short trip no, it would not be worth it at all. But I suppose if we had gone from Cusco we might well have done it the same as you did.
