hey,
I just moved to Atlanta about 10 months ago in the middle of summer and clearly it was hot. What Atlanta does have is a plethera of indoor playareas that are affordable. They have jumper or moonbounce places, for reasonable prices. My kids love Kangazoom. There are different playareas for different ages and open play all week. Its not overcrowded and kids get their energy out. There is another that was just bought out in Roswell called Jumpin Jeronimo. Have fun.
