You traveled a long way, wow! We haven't been there for several years. After Covid may plan to go back, if health allows us. Don't know if there can be slow time, but had to keep up with tour, and never had time to view some things. Hate being rushed, but place was busy, when we went.
The best time to visit is around Easter. Sadly Graceland has been sold, although the Presley's still have some say. The Graceland accomodation is far too expensive and not with the money. I can link you by PM to cheaper hotel. Do visit the Stax museum in Memphis, it is brilliant.
