To speed things up, you could take a taxi directly from the airport as far as Ollantaytambo, from where there are more trains to Aguas Calientes - which from Ollanta is only about an hour away.
The best months to visit Machu Picchu are May to October. Generally in Machu Picchu it is hot during the day and cold at night. The tourist must be prepared, because the weather has fluctuations. The ideal thing is carry a backpack,a sweater of wool, a jacket. During the day the tourist can use a t-shirt and a comfortable pair of pants.
