Just make sure you have the ability to melt enough water and stay warm at night. Super dumb mistake me and my friend made last year. We had a lot of camping experience but not much experience "up in the mountains" (It felt that way for us because we were the only ones with permits to go up that night). It is not technical but can be made super miserable if you do not have the right equipment. For the south side the right equipment would be a decent insulating layer at night, enough food, and water. Other than that, just make sure you stay on the trail and you should be okay. Just be safe and have fun. It is really pretty there!
