Freshman at Emory here.
In regards to the workload, there is plenty of time for partying – especially for business students. I went out every weekend last semester and managed to get nearly all A’s. It can be a lot of work sometimes but I always had time for going out.
I don’t think many students go to the GT games, although you could certainly go with your friends. To be honest, school spirit is pretty non-existent here at Emory. If this is a big deal for you, I’d recommend looking somewhere else. That being said, it isn’t a huge problem for me. Students are more “spirited” about things they are involved in (greek life, clubs etc).
There is a club called Outdoor Emory that would be perfect for you. They do weekend outdoors trips all the time and is subsidized by the school (I think). Definitely check them out its a great organization.
Lastly, in my opinion Greek life is a pretty big deal at Emory if you like to “go out” in a traditional sense. So make sure you’re alright with that before coming here, if that the experience you’re looking for. I don’t mean this in a negative sense, I really like the Greeks here I’m just putting it out there.
