Train
Train is a often a great choice for long-haul travel especially if you opt for a night sleeper train with berths which will allow you to
sleep all your journey through. To make the most of your train journey, choose the class of your ticket wisely.
Note that there are air-conditioned and fan-only carriages; private compartments for 2 or 4; hard and soft seats.
Though the upper class you get the smoother is your journey, often second class air-conditioned or fan-only sleepers are a good money saving alternative.
Van
Vans are a great alternative - or, in many cases - your only option - if you need to travel overland within one and the same province or neighbouring provinces or states. Vans ply the roads between Ollantaytambo and Machu Picchu, too.
Things to remember: When travelling by van with huge luggage buying a separate seat for your suitcase or backpack is a good idea. Do not expect there is a roomy luggage compartment in a van - there is actually none and your fellow passengers are unlikely to appreciate your luggage stuck under their feet, alas.
