Atlanta, Georgia tourist attractions?

I’ve read the other threads about Atlanta Georgia, and Little 5 seems to come up often. Here’s some more details though.

I’ll be travelling there with a friend of mine, and we are Canadian (just throwing that out there). So, we’re travelling there by plane. We’re both 19 years old, and don’t fancy bars or what not for this trip (I guess we’re not of age anyways.. for the states).

We’ll be at a loss for convenience of rides since we do not plan on spending too much money while we’re there (especially not to invest in renting a car, as our sense of direction would not be good there, and we’re surely to get lost, so, gas money would be wasted too), thus we’re not going to rent a car, and we’re staying at a relative’s house. We’ll only be there for 2 weeks, or a little more, one of our priorities is shopping.

What are some easy means of transportations? Is taking the bus appropriate? What is the fare on that?

Let’s hear some good shopping malls and large tourist attractions where it’s easy to walk from one place to another?

Our relative surely is able to drive us some places, but I do not wish to bother them out of their busy daily schedule, and lodging there seems to be great enough.

Thanks in advance! =)
