Route choice matters more than anything else. Marangu is the only route with huts and the shortest profile, which also makes it among the least successful for summiting. Machame and Lemosho climb higher and sleep lower, which acclimatises you far better — and every extra night on the mountain measurably improves your chances.
All our climbs use registered guides and porters, with crew welfare handled to the standards the park requires. Accommodation on the mountain is set by the route; the service tier mainly changes the hotel before and after, the support ratio and the equipment.
