We'd been on ACL once before & knew it was mucho dinero, but wanted to do Memphis-Nashville Music Cruise. This is the 1st yr ACL has attempted this route, & omigosh, the timing needs improvement! The brochure isn't nearly clear enough that you hafta get there EARLY to see the music sites in either town.
They offer Graceland pre-cruise ($$$), but no Sun Studio or Memphis Rock & Soul tours, etc. G'land gives u ONLY Elvis, & when they pick u up on embarkation day, u sit in the bus for 2hrs on tour without exit (until Bass Pro Shop visit).
You cruise up Mississippi lookin at trees only practically, shore excursions are coupla Forts or Museums.
