Sponsored by that famous soft drink brand? No. Coca Cola Route is the nickname for the Kilimanjaro route that is also known as the Tourist Route. This is not because there are no tourists on the other routes, but because the route is seen as an easier alternative.
It is easier, but it is certainly not easy. There are large differences in altitude per day, which can lead to acclimatisation problems for some climbers. In terms of comfort, the Marangu Route does make a difference. If you don't like camping, choose the Coca-Cola Route to Uhuru Peak.
The Mandara, Horombo and Kibo Huts are relatively luxuriously equipped. Well, you still bring your own sleeping bag and there is no running water at Kibo, but given you are at
Kilimanjaro, there is no reason for complaints.
