Atlanta is a lovely city, with many attractions that you may wish to visit if you have some free time.
The ACBL has prepared a page of attractions, which you can find by clicking here together with a list of some of the tours you could book while you are there ... click here to see that page. These are not just architectural tours, there is (for example) a Zombie tour which sounds great fun, or a Segway tour. There is a cycling tour for the cyclists among you.
There is an official site all about Atlanta, and that also has details of additional attractions and things to see - just click here.
The ACBL is planning several outings for the participants in the Championships - click here for more information.
