On the road to Tsavo East, I noticed the incredible amount of hotels lining the road. I can only assume that the hotel demand comes from the sheer volume of trucks that criss-cross the country every day. I don't think I've ever seen so many trucks to be honest* and at times they were lined up for kilometres waiting for inspection.
As you'll see, the accommodations are basic, but when compared to the alternative - a rolled over truck - I think stopping for a few hours is best. Enjoy!
