Well educated (MS, MBA) and travelled. Lived in U K, Kenya and S Africa. Retired (on limited budget but flexible schedule) and have used this service for 4 stays already. I am still reasonably active but no longer able to walk long distances without a break. I mostly take road trips - I have use of a car at destinations and can choose / vary hotels en route at short notice. In large cities I normally use public transport day passes so access to transit is important. I enjoy interacting with the local populace but don't come with a list of "must see or do's" - touristy stuff doesn't appeal to me.
