Hi,
18 months ago we decided to fulfill our ambition and visit Gracelands and Nashville. We booked our flights through United flew into Orlando and then an internal flight to Nashville, picked up a car then drove Nashville, Memphis and back down to Orlando. The drive was great we could spend as much time as we wanted in each place not rushed by having to catch a flight back, even drove down to Tupalo (Elvis's birthplace) and went round his museum there, spend time in Nashville, went to the Grand Ole Opre, would recommend it all to anyone. We only booked the first night in Nashville and booked into Fairfield Inns on our travels, no problems at all, the Fairfileds will even onward book for you if required.
Enjoy Nashville if you are a fan it's fantastic
Val
