This is probably of value only to people who stay at the Westin Charlotte since there are many better options Uptown. However, if you're staying in this hotel anyway there a a handful of 110v outlets in the parking garage. Nobody in the hotel seems to know it, but there they are. I am using one of them now, just maintaining my charge from the Charlotte Supercharger to the North. I am getting the typical 111v/12a/3mph, plenty for maintaining my charge just prior to a long trek southbound. The ones i have seen are facing the outside of the parking stalls, installed in the vertical support pillars and very obvious when passing by.
