Whenever you make it to Tennessee, there will likely be a great annual event happening nearby. If you show up during Labor Day weekend, you should look into Memphis hotels so you can check out the Memphis Music & Heritage Festival. This happens near the end of the high tourism season, so cheap flights to Tennessee will start to become readily available. The Memphis Airport is 11 miles from city center hotels, so look for shuttles.
If you arrive in the middle of summer, you'll enjoy the Chattanooga Riverbend Music Festival and the CMA Music Festival in June. Winter months are where you'll save more money on plane tickets to Tennessee, and fortunately, you'll still be able to see Gatlinburg's Fantasy of Lights Christmas Parade in December and February's Antiques and Garden Show of Nashville.
Maybe you're one of the spur-of-the-moment travelers who doesn't plan your trip based on seasonal events. If that's the case, you can always visit "The King," Elvis Presley, any time at Graceland. You can also catch a show in Nashville or witness the indescribable beauty of Ruby Falls in Chattanooga. If you are in Nashville, make sure to eat out. The city has been ranked as one of the top 40 U.S. cities when comparing food.
