We were there in May and stayed at the Marriott Inka del Tambo where the Urubamba train station is located. At the time the train was not running and no one could tell us when service would resume. We hiked the Inca Trail to MP. Then we took a train from AC to Ollantaytambo and then a taxi back the Inka del Tambo. I thought there would be plenty of cabs meeting the train but that was not the case and we had a bit of an issue getting one. I would recommend reserving a transfer.
